Hi William

   It is fairly easy to automate the installation of this (not 
necessarily using yum, though if you really want the nVidia drivers as 
an RPM package, by all means, it is possible ... and then yum will work).

   Is this of interest for Cuda/Nvidia users?  If so, what ABIs, and 
distros?
