The PPA kernel behaves differently:
Linux lvm-laptop 2.6.32-16-generic #23~drm33v5-Ubuntu SMP Thu Mar 4 17:21:31 UTC 2010 i686 GNU/Linux
1) Power off and close Laptop (T61 or x61)
2) Place laptop in docking station
3) Turn on laptop via docking station power button
4) Login and start a session
5) Press the undock button
6) Remove laptop from docking station, laptop will suspend
7) Resume laptop, but it will go back to sleep (not subject of this bug report)
8) Resume laptop second time
9) Session is restarted
The dmesg contains traces of drm:915 driver:
