I tried this out recently for Fedora core 7 (FC7), without having to rely as much on the Fedora FAQ site.

First run these commands where "X" is your current Fedora core version.

Code:
# rpm -Uvh http://rpm.livna.org/livna-release-X.rpm
# yum -y install kmod-nvidia
# init 6
The drivers don't always get loaded with the Kernel unless you do a reboot. When your system reboots, get into text mode with the "init 3" command.

Code:
# init 3
Follow tuxette's method.
