It's a PCI Express card. I filed a bug here a while ago that contains all 
kinds of logs and a link to a smolt profile:
https://bugzilla.redhat.com/show_bug.cgi?id=553059

(I have to use "nouveau.modeset=0" for booting in that bug because without 
that the F13 doesn't boot at all. See
https://bugzilla.redhat.com/show_bug.cgi?id=530784
for more information on that.)
