Ok I read a ton on modifying kext -but I jsut cant wrap my head around it.
My system is running great except for this.

my video card is working but only one display works.
Plus on my "about this MAC" under graphics hardware it reads this
ATI Radeon HD 4890:

Chipset Model: ATI Radeon HD 4890
Type: GPU
Bus: PCIe
Slot: Slot-1
PCIe Lane Width: x16
VRAM (Total): 4294965248 MB
Vendor: ATI (0x1002)
Device ID: 0x9460
Revision ID: 0x0000
ROM Revision: 113-B7710C-176

Pixel Depth: 32-Bit Color (ARGB8888)
Main Display: Yes

Notice my VRAM size -its way wrong -it should only read 2gb or 2048 mb -I believe this is why Im getting a -VRAM issue when installing Final Cut 7

My Device Id and Vender # are right --I looked those up. I have read a ton about entering the correct numbers in the ATI4800Controller.kext but I dont know how to do that and I have read and read and still dont understand.

That is the ATI4800Controller.Kext
Where do I put in the info

Can anyone help me fix my problem.
