After Running the terminal commands you posted I wasn't able to reboot so the commands weren't able to correctly make the hex changes for me.
What I did instead was edit a backup of the two files directly with HexFiend and it is working perfectly. Tested with LuxMark 2 and my Quadro 4000 now is running Open cl 1.1.
I have a Mac Pro 3.1 with Lion 10.7.3
Performance with Final Cut Pro X and Motion feels much faster now, woot.
If anybody tries this and in case of problems, be sure to make a backup of the GeForceGLDriver and have an alternative boot drive in case you have to restore the original file.
Below is the files and the hex changes I made.
EB A8 83 F8 02 7C 15 replaced by EB A8 83 F8 03 7C 15
78 E8 83 F8 02 7C 11 replaced by 78 E8 83 F8 03 7C 11
8B 87 1C 0C 00 00 89 06 8B 87 20 0C 00 00 89 02
31 C0 FF C0 FF C0 89 06 31 C0 89 02 90 90 90 90
I installed the Quadro 4000. I had the latest drivers and Cuda installed from the Nvidia site. I had a Geforce 8800 that iI took out.. The performance was not as good as the 8800 with those drivers. I called Nvida, but I couldn't get anyone anyone to phone me back. The online chat is a joke. They know nothing. I called PNY, they told me that the old drivers from Nvida won't work properly with this card and 10.7.3. They said that Apple has the driver's built into their 10.7.3 update. PNY told me to start from scratch and do a clean system install. I did that all last night, and had to reinstall all of my software. The card still doesnt work. I don't believe that Apple has the driver in their update. I'm going to send the card back.
Listen. There is two drivers. One is the regular driver and is built in to Lion 10.7.x
The other is the Cuda driver which is for the accelerated rendering.
The main performance driver is most certainly included in Lion and it works well.
The Cuda driver will show up in your System Preferences as a Preference panel.
You need to download it from Nvidia. After that you can update it through the Preference.

Can someone explain to me how I find these lines of code, with HexFiend? It seems there are 7 pairs of letter/number combinations, but all Im seeing in Hex Fiend is groups with 4 pairs. Where do I find these? Do I have to scroll through all the lines, searching? does anyone have a line number?
That code I posted was from 10.7.3 If you have a different version of the OS it might have different drivers.
In hex fiend press command f to open a search window. Make sure hex is selected and enter the whole group of code to search for. As an example you would paste EB A8 83 F8 02 7C 15 in the search box and it will find it. Then just replace the found text with EB A8 83 F8 03 7C 15. Make sure you don't delete or add any additional characters. The edited binary file must contain the same amount of bytes as the original.
Be careful and make a backup. Don't edit the files directly in your System folder. Make a copy to edit.

I came across this thread a while back when I bought my Quadro 4000 and was surprised to see that OpenCL wasn't enabled on it. You guys may know this by now, but Apple re-enabled OpenCL for the card in 10.8. I updated on Friday and I can definitely see an improvement in performance. There didn't seem to be much info on this so I figured I pass it along
