Thanks Rune,
radeontool in Jaunty* can be used to assist in debugging these kinds of
issues where the screen blanks on start. 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 working screen (for any driver),
and once in the broken case (either from the tty console or logged into
the sick box remotely). Attach both of those to this bug report, and we
can then forward this issue upstream. Thanks ahead of time!
[* Note: radeontool is available in earlier versions of Ubuntu but is
too old; if you need to run it on an older version of Ubuntu, you can
obtain and build it from the upstream git tree at
http://cgit.freedesktop.org/~airlied/radeontool/]
