Ok, cool.  That confirms that it's a bios->drm video handoff problem.

The degradation may not be anything that you care about. :)  Not doing the
video handoff from bios to kernel means there will be additional flickers
(and possibly resolution changes) at boot time that we have tried to
eliminate.

Bug description:
  After installing Ubuntu I can't boot into the OS at all unless I manage to get into recovery mode (which is very hard with no timeout on GRUB by default) and install FGLRX from there.
  It happens on every version of Ubuntu that has the open source drivers for the AMD Radeon HD 6850 graphics card installed.
