If you don't know what you are doing, then don't burn a kernel. I've
been using Linux for some years, 
and burning a kernel can be highly problematic. I just successfully
followed the instructions at:
http://rpm.livna.org/configuration.html
http://www.stanton-finley.net/fedora_core_5_installation_notes.html#nVidia

  ...and it works. Read both sites to get all the information for your
setup. The livna install requires that the kernel version match the
nVidia driver version. So, the process will install a kernel for you if
you don't have the correct kernel installed. All in all, it's pretty
straight forward, IF you follow the instructions. and allow it to work.
I'm happy as a clam now that I have it up and running. Ric
