mjg59 says that -vesa just doesn't have edid hooked up, thus the 0mm x
0mm.  False alarm.

"VBE call failed"  Rats.

Anyway, my guess is that something's wrong with your EDID, but without
being able to actually see it I can't be sure.  It could  just be a
general modesetting issue, or even just some other random bug in the
display logic.  I see you have an LPL monitor - which is a brand we've
had to quirk around in UMS before, so this strikes me as a strong
possibility.

Unfortunately, a lot of the techniques we would use to debug this in the
pre-KMS days simply won't work anymore since the kernel doesn't provide
a way to do the equivalent of overriding modelines and other settings in
xorg.conf.  (So even if we do get the EDID, I'm uncertain how to test
theories, other than hacking on kernel code...)  The old debugging
approach is documented at http://wiki.ubuntu.com/X/Quirks - pretty much
the same quirks exist in the kernel, but I don't know how to turn them
on to test, aside from adding the code to drm_edid.c.

Anyway, I could be completely in left field.  Maybe RAOF will have some
better suggestions.
