10.6.4 and 9800 GTX+ enabling quartz?

[exempt]

I have my hackintosh setup working, for the most part, I used a Iatkos S3 V2 install. Everything works the ethernet, audio, pretty much everything but Final Cut Pro and a few other apps run like poo because the apps say the GPU has 0 VRAM. However I get this just fine:

Chipset Model: GeForce 9800 GTX
Type: GPU
Bus: PCIe
PCIe Lane Width: x16
VRAM (Total): 512 MB
Vendor: NVIDIA (0x10de)
Device ID: 0x0612
Revision ID: 0x00a2
ROM Revision: Silent Natit x86_64 v1.0.2
Displays:
Display:
Resolution: 1280 x 960 @ 60 Hz
Pixel Depth: 32-Bit Color (ARGB8888)
Main Display: Yes
Mirror: Off
Online: Yes
Display Connector:
Status: No Display Connected

I know it has something to do with enabling Quartz Extreme, and I know that people have done this with the 9800 GTX /GTX + so can someone please explain what I need to do in order to get this working properly?

I really appreciate any help thanks!
