I may not have added it to NVDAResman, come to think of it, as I only remember adding the device/vender ID to one kext.

I will try that now.

Edit: I'm sure now- NVDAResman info.plist still shows stock value for IOPCIMatch... let me update and reboot.

Edit 2: Added info to IOPCIMatch in NVDAResman.kext info.plist.

No change in situation- Halo running full screen still is just static. Still doesn't lock up pc (can hear mouse over sounds from menu options, forcequits to desktop and restores screen).
