Regarding the installation, yum install should take care of
dependencies for things like dkms.  dkms intern pulls gcc and
kernel-devel among other things.  There is one potential issue here.
If the user is running a non-standard kernel (such as xen), then
kernel-devel must be installed manually (kernel-xen-devel, for

If you are going to delete the nvidia driver to do a simulation, I
think rpm -e removes *most* of the stuff installed.  I say "most"
because, the original installation of nvidia.ko may have created
symlinks in /lib/modules/ and these symlinks are apparently NOT
removed by the uninstall script of the nvidia rpm.  This may no be so
important for your testing but just in case.
