Hi Dana, okay, radeontool might be useful in debugging this. After
installing it, you run it like this:

    radeontool regmatch '*' > regdump_good.txt

    radeontool regmatch '*' > regdump_broke.txt

Run it two times. Once when you have a good, working screen (for any
driver including -vesa), and once in the broken case (either from the
tty console or logged into the sick box remotely).

** Changed in: xserver-xorg-video-ati (Ubuntu)
       Status: Confirmed => Incomplete
