Not quite the same issue, but might be of help or point you in a useful
direction.
I had a monitor that had a bad checksum in the EDID, so it would only work
at 640x480. I was able to fix the issue by extracting the EDID from the
monitor and fixing the checksum, then saving it to a file. I then
configured Xorg.conf to use the file instead of the one it would read from
the monitor. ( I later just fixed the checksum and re-wrote it to the
monitor so I didn't have to deal with this hack )
Here are instructions on Nvidia's website.

You might be able to use this to tweak the reported capabilities of the TV
to be usable. You can use 'read-edid' to get the edid from the TV then
edit it with a hex editor.
Hope this is of some help,
I'll give it a try tomorrow. Maybe if I play with the MetaModes values
I'll find something that works.
Thanks.
