Re: kernel 2.6.11 problem.
Disable CONFIG_DRM (Device drivers->chraracter devices->Direct Rendering Manager). That's really only good for non-nVidia cards (Radeons, etc). Enabling the kernel's AGPGART driver is optional, the nVidia driver includes one that may or may not work better for your motherboard.
