Jan 15, 2011 2:08 PM in response to SeSamby KrzysiuTurek,@SeSam - A strange thing, if I understood correctly, it does not have anything to do with changing kext files - but with RAM modules. Look at this:

http://support.apple.com/kb/HT2341
I hope I'm wrong, and everything will be ok with the RAM -
Jan 15, 2011 4:15 PM in response to KrzysiuTurekby yogidig,Sorry that it has taken me this long to reply.. I tried 10.6 kext and all I got was a gray screen.. I got out of it by pressing the shift key and booting into an external HD (I did the new installation to get the ket files in my external usb drive). The I tried 10.6.2 and I got the screen with a message telling me to reboot. I rebooted a couple of time and I got the same message. And now I'm back in 10.6.6 9 (I reinstalled the bundle and so far no issues). So you know, my machine froze up the last time with a temp of 72ºC (fans running a regular speed), while I was using Aperture. I'll try again and see if it freezes again.
BTW, I have a NVidia GPU

Jan 15, 2011 5:24 PM in response to KrzysiuTurekby Tim Isham,I used this fix on my 20" imac 7,1, and it seems to be working so far. The first time I got a kernel panic, but then I noticed in your original post that you had a different iMac than I do. I looked up the video card for my machine, and repeated the procedure using the ATI2400Controller.kext file instead of the ATI2600Controller.kext file and it worked. Has not crashed so far.
For those interested, when I used the wrong kext file the first time, I was able to boot using the install disk. I had another partition on my disk with Tiger installed, because Snow Leopard had been freezing so frequently. One must get one's work done...
Thanks so much! I will send feedback to Apple, hopefully they will fix this in a future update. -
Jan 15, 2011 5:52 PM in response to Tim Ishamby KrzysiuTurek,@The Isham - This confirms the every file must be in the same version, otherwise it would not work.
@yogidig - could you tell what kind of gpu you have and which file you replace
Could anyone confirm strange behavior of Finder after kext replace/10.6.6 update.A few minutes ago I had to manually shut down the computer after Finder crash. -

My RAM is fine. The Mac does not beep, the sound is the generic tri-tone Mac bootup sound. -
Jan 16, 2011 12:51 AM in response to KrzysiuTurekby Vurey,On a related topic, I contacted AMD customer services regarding a fix for the graphics cards. This was the response I received:
+Dear Customer,+
+Your service request : SR #{ticketno:[8200381703]} has been reviewed and updated.+
+Response and Service Request History:+
+We apologize for any inconvenience. Please note that for embedded cards in a Mac system, we only provide the driver for the first revision then it is up to Mac to provide the updates . Please contact Apple for any driver update issues directly..+
+In order to update this service request, please respond, leaving the service request reference intact.+
+Best regards,+
+AMD Global Customer Care+
Looks like we'll have to wait for a fix from Apple. If that ever materialises. -

On what planet does this make sense?
So ATI/AMD makes a standard video card to embed in Apple systems, creates the first round of drivers and then tells Apple that they are on their own from that point forward?
No wonder Apple has been pushing for embedded graphics lately! I would too. While I will give credit to Apple in the graphics department, I by no means believe that they have the same deep knowledge of ATI's graphics cards as they do. There's just no way they are going to nail this bug down without their help.
This doesn't give me much hope for a fix - without support from ATI I doubt they will put much energy or manpower into investigating a fix, especially when they are not the company that wrote the software to begin with.
The move towards the A5 and Intel's new integrated processor/graphics combo chips are making a WHOLE lot more sense now. Good on you, Apple. Get rid of these goons. -

Jan 16, 2011 5:16 PM in response to SeSamby yogidig,@SeSam I don't know if this may help you, but I booted my machine to an USB drive by pressing shift just after the boot bell was done, and then copied back my good kext. My machine was also booting to a gray screen.

Jan 16, 2011 9:45 PM in response to DazzaGby Eminemdrdre00,It's definitely a problem with the video drivers. I have an iMac8,1 with an ATI Radeon HD 2600 Pro and I did exactly what KrzysiuTurek said to do. I've been running 10.6.6 flawlessly for the past week. Before his fix, my iMac would freeze on anything higher than 10.6.2. As he pointed out, it's because 10.6.3+ ships with different versions of the video drivers.
So what's next? KrzysiuTurek found the problem, how do we let Apple know? -
Jan 16, 2011 11:03 PM in response to Eminemdrdre00by jzelko,Hi everyone!
I am under the direction of Krzysiu Turek made yesterday and so far I doing well. I think that it is not so dangerous, if careful, to the proceedings. So far, said after the update has served more than two days, I hope that it will now longer. If a man thus saved me hassle!
Tell after a few days how things are going. Hi.

Jan 17, 2011 11:23 AM in response to yogidigby SeSam,Holding down shift is supposedly safe mode, in my case the Mac's stuck on the same white screen regardless.
I tried Firewire Target Disk Mode today, but no success. I had white screen for about 5 minutes then finally the Firewire icon appeared, but the host computer (MacBook) didn't see the drive. Also, the Firewire icon was moving on the screen really really slowly, like one frame per minute. Normally it should ping around the screen.
Seeing how everyone else is doing well this may have nothing to do with me experimenting with kext files. -
Jan 17, 2011 11:34 AM in response to SeSamby yogidig,@SeSam, my mistake, I meant the Option Key.

Jan 17, 2011 1:59 PM in response to DazzaGby TeardropCarnival,Hello all,
I've been reading this discussion for a long time, first time posting. I've had this issue since 10.6.3.
I tried the fix a few times before getting it right.
Just a note to anyone attempting the fix, be sure to check which Graphics card you have before applying the kext files. I have the 2400 while I had been applying the kext file for the 2600. This resulted in my iMac freezing on the grey screen (the spinning wheel would just stop). After having to boot from install disk, reinstalling 10.6, installing 10.6.2 combo, two separate times, I think I'm in business.
I'll report back if things go south.
Thanks to everyone for hanging in there and helping out. Hopefully 10.6.7 will give us the official fix for this ongoing issue. -
Jan 17, 2011 2:21 PM in response to DazzaGby balintalovits,Does f**king apple care about our problem? I reported this issue a several times, but they do not give a sh*t!
