Have a look for EDID. This is the info that xorg gets from the
monitor. You should be able to extract it manually, and there are
tools to create the correct file for it. Then you can add an option to
your config file for x that uses this information. It was some time
ago that I was playing with this, but I know EDID is one option open
to you.
