This site has a lot of good info regarding video drivers, both nVidia
and Catalyst, on RHEL and clones. I didn't see anything regarding v6.2
clones specifically, but there are step-by-step instructions to
installing nVidia on Fedora{16, 15, 14, 13}. Also good info on mozilla,
eclipse, oracle java, virtualbox, adobe etc.

Good luck.
