On Fedora 13+14 (x64) the Nvidia driver just crashes, if not 
immediately, within a few minutes, however, if I compile my own kernel, 
from kernel.org (and built the nvidia driver from source) it's perfect - 
applies only to x64.

Does lspci show the card at 01:00.0, it may not be finding the card.

best of luck..
