If you can grab Boot Camp 3.0 thru 3.x you should be able to get the drivers you need.
Apple took more agressive steps to really lock out and lock down drivers from being used and installed on systems that did not fall under the guide of 'supported'.
So if you have 10.6 DVD that does have Boot Camp 3.0 on it and you would need to update to 3.2, which use to be posted for manual download (so could do so even from Windows) if not thru the Apple Software Update utility in Windows.
If you can find a more "no we won't allow you to" I have never seen it.
And Google as best you can.
Finally I decide to install windows 7 32bits. But now I have a new problem with the bootcamp.
When I try use alt option to run windows 7 I get a black screen blinking cursor.
If I go to MacOS and check boot option but I only see the MacOS partition...
I have a SSD with two partition one for the MacOS and another for windows7
brauliom, did you format the partition during the windows install? If it's not formatted by the DVD during the install it will not boot, and won't show up as a bootable option from within >System Preferences > Startup Disk...
Hope this helps, although looking how old the thread is you've probably sorted it by now...
Well, I don't know if you still having troubles with the bootcamp drivers installation but I have found the solution in this post: http://michael.anastasiou.me/boot-camp-x64-is-unsupported-on-this-computer-model / I hope that it is still useful for you or for anyone who wants install Windows 7 64 on mac by using bootcamp!!
