I agree. One problem is that these things are all different,
almost completely undocumented, and implement non-standard
modes seemingly at random. Some people involved with various
OSX86[0] efforts have developed methods for probing (and in
some cases, modifiying) the VESA BIOS on some cards. All
kinds of strange behaviors have been observed.

I haven't made any attempt to catalogue VESA vs EDID
discrepancies, but I do keep a small archive of hardware
info here:

We try to collect the sysinfo[1] output for as many
systems as possible, for later reference.
