problem with XFree86 in testing

[Caitrin Torres <caitrin@artemista.com>]

I upgraded my laptop from stable with a few testing packages to all 
testing via an accident with dselect last night. The next time I 
booted, I realized that X had broken. Running startx results in a 
half-inch flickering band on the left side of the screen, and nothing 
at all on the rest of it. I have to use ctrl+alt+backspace to get 
back to a prompt. Before the upgrade I was not having any problems 
with X.

I've never had X work less than perfectly before, so I haven't any 
idea where to start troubleshooting. Any suggestions of things I 
ought to try?

It's a Dell Inspiron 5000, with an ATI Rage Mobility P card, using the 
laptop's builtin screen only (no external monitor). Also, while I 
generally use KDE, I tried starting Enlightenment instead and got the 
same results.
