I've tried 2.6.11-mm1 and it doesn't reboot, I always (4/4 times I've
tried) get the behaviour I reported before where the video mode is set
and after that the screen just keeps displaying the garbled
framebuffer and nothing happens. The system doesn't hang though, as
I've found out by running "sleep 90; reboot" before starting X - after
the timeout my machine properly shut down. I inserted a "ps ax >
foo.txt" before the "reboot", and it showed that the X server was not
running. Then I found this in /var/log/messages:
