Public bug reported:

Binary package hint: xserver-xorg-video-ati

This bug is referenced upstream.

An annoying problem is that the gnome power manager must try and change the backlight brightness while loading the live session user, thus the live CD/USB just freezes a short time after X is up.
Maybe an exception could be added to disable KMS for this chip for Lucid and avoid the freeze ? UMS works fine with acceleration.
