Devices up to and including 05:00.0 are in the laptop itself, and everything
below is in the dock station.

I have tested the laptop with linux-3.10-rc5 with this patch series applied:
https://lkml.org/lkml/2013/6/13/349

The testcase is: boot with the dock station attached, let Xorg start (it will
use both Intell and Radeon cards), switch to a virtual console, press the
Undock button. Yes I know that GPU hotplug is not yet supported in Xorg, but
attempting it should not lead to messages like "kernel BUG at
drivers/gpu/drm/ttm/ttm_bo.c:1591!"

The part of the dmesg after the undocking attempt, captured over netconsole, is
attached to this bug.
