I've had a different problem, and several others have reported it I
think.  DDC/EDID are reporting good-looking timings (as far as I can
tell), but they get ignored.  Putting the equivalent modeline into
xorg.conf, the mode becomes usable.

In your xorg.conf output, do you see appropriate timings being reported
anywhere for your larger video modes?
