Need to get three drivers.
They are all available from nvidia's site.
Do a text install . . .
once you have installed (Making sure not to start in Graphic mode)
install the 3 rpm packages listed above.
then in /etc/X11/XF86Config
find the line that says "nv" and change it to "nvidia"
then in /etc/inittab
cahnge the initdefault line to be init 5 and not init 3.
if you have hassles then reboot in interactive mode and do not start the firstboot service .... that will give you a chance to login on one of your tty's
I hope this helps
