Am using x86_64 version of FC3 and had a few troubles post install. My PCIe (6600 256mb) was the problem. I used your method to install driver ver.7167 (as all others gave me artifacts etc.) and it pretty much worked, but a few amendments were necessary...
'rpm -e --nodeps xorg-x11-mesa-libGL' returned an error, could not use.
Added 'modprobe nvidia' to /etc/rc.d/rc.local
Reboot had to be via 'shutdown -r now'
But your thread helped immensely, so thanks
