I am seeing a similar, but slightly different problem which I bisected
to that same commit. I am using radeonfb and the radeon X driver and I
can log into kdm with no problems and work, but once I switch to a
'normal' console with CTL+ALT+Fn when I switch back to X it is dead with
the top, approximately 1/3, of the screen corrupted and keyboard and
mouse dead. I can get out of it by SAK+K which kills X and returns to
the kdm logon screen. There are no ooops or any other indications apart
from logging the SAK action.
