Howdy,
kind of an interesting and similar result here. Clean install, everything else works but the graphics. I fail to boot with GraphicsEnabler on, no matter if I use Vervet or Hoolock. With the enabler being off, I get an 5MB "Display" and fancy visual glitches all around. Patched kext method and using Chameleon r2278 with a Gigabyte GV-677UD-1GD on 10.9.3.
E: Nevermind, Kext Utility fixed it. Surprising how Kext Wizard and Disk Utility is supposed to help with it and doesn't really fix that...
