enabling QE/GL on XFX Geforce 6800GT 256mb

I searched the forum and the internet but have been unable to find a fix for this problem.

I used this wonderful guide to install the retail DVD. Gigabyte G31M-ES2L Retail Tutorial →

After a ton of trouble and and several reinstalls I got my card to let me change resolutions by updating to 10.5.8 and using "nvinject 0.1.3 VRAMtotalsize." However, I cannot enable Quartz extreme or Open GL. The machine is usable but ideally I wanted the Open GL acceleration for Photoshop cs4.

I tried enabling QE/GL using osx86 tools utility, but it had no effect.

Also in the system profiler it seems to have the wrong info about my VRAM size.

I have found these forums extremely helpful during this build and I hope someone can give me a little more specific insight for this. Thanks.
