The problem does not happen if you don't configure updates during
install (and run yum update before adding nvidia-graphics from
atrpms). It's also timing-sensitive, if new kernel update appears the
problem goes away. That's what happened with one of my systems, after
install I did yum update and a new kernel was installed, then I added
atrpms repo, and everything was fine.
