post 2.6.34-rc5 breaks integrated intel graphic at ThinkPad T400

[Toralf F. <tor...@gm...>]

Hello,

something between c81eddb..d5a3045  breaks my system. As soon as xdm or startx 
is started, the (external) screen is black. Neither Ctrl-Alt-Del nor any SysRq 
keys are working anymore.

The system has a GM45 chip set.
