nouveau/linux-2.6 branch linux-3.17
(I have honestly no idea anyore which branch one should follow/test in the last
months...)

Reproduce:
* Laptop in ThinkPad dock, lid closed
* external monitor attached to DVI connector on dock
* suspend (from Gnome)
* resume
* external monitor gets no signal
* opening lid does nothing, have to take out the laptop and laptop LVDS
activates
* putting back into dock gets in previous error state as after resume

Setup:
ThinkPad W520 4276CTO NVC3 (2000M)
openSUSE 12.3 (64bit)
