If you <Ctl-Alt-F1> can you get a login prompt? If so, look
at /var/log/dmesg, /var/log/messages and /var/Xorg.0.log (IIRC).
There may be some clues in there. Comparing the Xorg log to a previous
version might yield a clue.
An lsmod to see if a radeon module has been loaded? Keep an eye out for
radeonfb as well. DRI is supposed to be unstable with radeons (although
I run it NP). Keep an eye out for that and make sure the Xorg log shows
it is disables.
Go to /etc/X11 and see if an Xorg.conf exists. If so, look at it and
sett any resolutions to lowest/plain vanilla to start with.
