Bug#661943: xserver-xorg-video-radeon: Unable to set native resolution with KMS enabled

Attached is the Xorg.0.log from a boot with only 1 monitor attached.  Interestingly, when I boot with only only 1 monitor, I never get to a resolution I can use.  It stays on the invalid mode.  It doesn't matter which monitor I use.  Both produce the same result.  The only reason I have been getting a resolution I can use is because I have 2 monitors attached.

I think the console is trying to use the native resolution (which produces the "invalid mode" message), since sometimes the screen goes black before the startup messages get to the part about KDM (I assume that is when X starts).  I never see the startup messages in a different resolution than what they start with.
