Using NVIDIA drivers 185 and fakebios option in grub.cfg - I now have ACPI (2 cores, battery status) and 3D effects! applesmc is not working, mouse key emulation has disappeared (not a bad thing, I have my F11/F12 keys back!) - thank you everyone! I'll double-check my grub.cfg and then post that and my build script.
