I'm currently (slowly) collecting standard properties for RandR 1.3 that
should include stuff like this. Please feel free to help figure out what
other stuff you'd like to see pulled from the EDID block.

Not that we shouldn't also create an external EDID parsing library for
other things, but it sounds like the information you want for this
should be provided by the server in a non-EDID dependent fashion.
