Sure I can. 
I don't know which bootloader you're running but even if you've selected PC_Efi v8 on Setup, I would recommend to update it to at least v9 before you continue - if you're running the Darwin Bootloader this would be essential.
Then create a back-up of your /Library/Prefernces/SystemConfiguration/com.apple.boot.plist
Get the latest OSx86 Tools, open them and choose "Add EFI String / Boot Flag" Option, click "GFX Strings" - if you have 512MB you can try if the predifined 9800GTX one will work for you, otherwise select "Custom GeForce", first field is freeform, second your VRAM, the last your output configuration. Next select "Import String to Boot Editor" and "Apply changes to com.apple.boot.plist"
(If it doesn't take effect immediataley you might have to copy your boot.plist to /Extra folder first.)
