I have to do the same thing, fool my xorg to produce the correct
resolutions. Attached is my xorg.conf that includes a couple of custom
modelines (one uses the older multi-line mode format) and the needed
flags to make xorg play nice. My modelines feature standard 1080i and
540p timings and a reduced screen area that exactly matches the visible
portion of my monitor so they may look weird.
