My 2.6.36-rc8 .config-uration and miscellaneous info

I haven't been running NVIDIA GPU on this computer for almost a year, but I do
remember that this option wasn't necessary last time I ran this video
accelerator.

Without this option my GPU doesn't get assigned any interrupts and I'm met with
this message upon trying to run X server:

(EE) NVIDIA(0): The NVIDIA kernel module does not appear to be receiving
(EE) NVIDIA(0):     interrupts generated by the NVIDIA graphics device
(EE) NVIDIA(0):     PCI:5:0:0.  Please see Chapter 8: Common Problems in the
(EE) NVIDIA(0):     README for additional information.
(EE) NVIDIA(0): Failed to initialize the NVIDIA graphics device!

/proc/interrupts inspection reveals that indeed NVIDIA is not listed there.
