Graphical video not working after yum upgrade from fedora 11 to fedora 12

[John Nissley]

I had an up to date fedora 11 install that was working fine.  I followed 
the instructions on the wiki for doing a yum upgrade and everything 
seemed to go very well until I rebooted and things hung as the graphical 
interface (I use KDE) was to boot.  I am able to boot into single user 
mode and run level 3 and things appear to be fine.  I just can not get 
the graphical display. Any help would be appreciated.
