This set up is pretty solid.Using EFI v8 it has fixed my NForce Lan freeze by using the forcedeth_nockd kext. The only things not working now are PS/2 (It freezes the entire system if I attempt to use the PS/2 Keyboard, as in if I try to type on it.), the DVD-Rom refuses to eject after being used to install programs (System profile, Disk Util, and Finder all freeze after trying to eject, and sleep the machine won't goto sleep properly. All Eject attempts don't work.) and So far the only program NOT working is iMovie 8.

Edit: It appears the NForce Lan Freeze still exists it was just hiding from me.
