--- Comment #5 from Ilia Mirkin <imirkin at alum.mit.edu> ---
OK, so this has nothing to do with setting the PreferredMode. Good, that would
have been weird. Something's not being computed correctly. I wouldn't be
surprised if the mode data in the EDID were somehow wrong for those modes, and
other drivers are just better at dealing with the incorrectness. Or perhaps
we're setting some clock incorrectly.
