somewhere before commit 496322b (yesterday's kernel) resolution 
switching on my laptop broke. The screen switches to the right 
resolution but the screen is not horizontally centered. The screen is 
aligned left and the last vertical line is repeated until the right side 
of the screen. Normally there would be black bars on left and right side.
