I have two screens one 4:3 and one 16:9, since Linux 2.6.33rc1 the "spare" space (bottom of one screen, on the right on the other) between two have been filled with white in the console. (Other than that everything seems to work great). Maybe change the color to black?
My card: ATI Technologies Inc RV770 [Radeon HD 4870]
It was filled with black on Linux 2.6.32.x .. :)
Not sure if this is the place to report a KMS/kernel related problem, if this is the wrong forum please push me in the right direction..
This seems to be fixed in 2.6.33rc8,
have not tested the commit explicitly, but looks like 6719fc663c6cd30da5dd02d08aaefb031a7a98fd did the trick for me.

drm/radeon/kms: fix screen clearing before fbcon.
This memset_io was added to debug something way back and got
left behind, memset the fb to black so the borders don't be all white.
