At this time i have not found out how to use nvidia module with SELinux enable. If you know how, feel free to add to this post
Any suggestion is welcome

I don't know how to set up the driver for SELinux, but I was able to set it up in Fedora Core 4 in an easier manner (without yum, but i may not have done this right).

-Download the driver
-Press Ctrl-Alt-F1 to get a prompt
-type init 3 (if a prompt doesn't come up press Ctrl-Alt-F1 again)
-go to the directory and run sh (nvidia driver version).run
-after setting it up reboot the machine

glxgears went from 500fps to 1500fps (on nvidia 6200 agp).
