Subject: should the resoltion of a closed lid of a docked ThinkPad be considered

Hello,

there's a different behaviour between 2.6.33.3 and 2.6.34-rc5 observed at a 
ThinkPad T400 with intel graphic GM45 .

If it is docked and the lid is closed (1440x900) and an external DVI monitor 
(1650x1080) is connected at the docking station - the dmesg of 2.6.33.3 gives:
	Console: switching to colour frame buffer device 210x65
whereas 2.6.34 gives:
	Console: switching to colour frame buffer device 180x56

Furthermore X differs in the fact, that 2.6.33.3 sets the external monitor to 
the expected resolution:
	(II) intel(0): Output HDMI2 using initial mode 1680x1050
whereas 2.6.34-rc5 sets it to the (unwanted) lower resolution :
	(II) intel(0): Output HDMI2 using initial mode 1440x900

Now I'm wondering whether this new behaviour is wanted - and if not - which 
mailing list is the correct one ?
