Thanks for the suggestions.

I used the HDMI output with a TV to get 1920x1080 resolution, so I agree
that it's not the video memory.

On my old, old linux system I would manually enter the available
resolutions in my xorg.conf file; the monitor is definitely capable of
1280x1024 resolution, both according to my memory of using it with
ancient versions of debian and ubuntu as well as from reading the
technical specifications for the monitor online (Samsung SyncMaster
930B).

I have attached the errors produced by get-edid as Moritz suggested. I'm
not sure how to read it, but I suspect this is the interesting section:

=======
VBE/DDC service about to be called
        Read EDID

        Performing real mode VBE call
        Interrupt 0x10 ax=0x4f15 bx=0x1 cx=0x0
        Function supported
        Call failed

The EDID data should not be trusted as the VBE call failed
EDID claims 19 more blocks left
EDID blocks left is wrong.
Your EDID is probably invalid.
=======

I next tried looking at the firmware, which gave me the lshal.output
file. I'm afraid that I don't know quite what this information means,
but it looks like it may be the same bug reported by Moritz earlier. So,
here's a confirmed on the bug existing.

Thanks,
Brian
