Comment(by andreasf):
I've added an RFC for reading the EDID. Unfortunately I could only
''guess'' how the EDID info relates to the numeric modes needed for
{{{set-mode}}} - for my Radeon 9200 the established timings for VGA,
followed by the established timings for DVI (labelled "LCD"), then a few
more (but odd number). There's a {{{mode#}}} to retrieve the current mode
though, and said {{{show-modes}}} to print the modes on-screen.
