I saw the same problem recently after I switched from analog to DVI
output, but don't know exactly what caused it. The xorg log ended
with "no screens found" or something to that effect. No amount of
working with xorg.conf would get it to work, even a pure generic
xorg.conf would bomb out. I ended up reinstalling MythDora from the
DVD, running 'yum update', and now it works perfectly from DVI.
This was a FE only system, so reinstalling was pretty painless for me.
Not sure if your setup is the same.
