The nouveau driver had issues during boot, caused plymouth to have indigestion
and fall back to 24x80 character mode. This happened sometime between
-mmotm0422 and -mmotm0428. Looks like something in linux-next, cc'ing
anybody who apparently touched nouveau code. Will bisect if nobody has
a good idea what happened.

The X server was able to init the card and get gdm started just fine.
