I can report unequivocally the success of the GFXString hack for com.apple.Boot.plist! I followed an excellent tutorial I found on the Interwebs (can link if so requested), that outlined how to extract the Hex string for my GFX card. I did follow the instructions, plug it in my plist and repaired permissions, and voila, after the reboot, I logged into my Hackie without standing on NVInject’s shoulder! It feels just so liberating, and I can already report a certain rise in GFX performance as I navigate through the Spaces and Expose. Tally ho!
