That code is also shared by rivafb. It's rather LCD/DFP specific for
now, I would _much_ prefer some more generic EDID parser. So far,
I haven't been able to find any specification of the edid block,
this is annoying as I'd like to deduce a proper default mode for
CRTs as well, and some informations about backlight ranges (if any
in the EDID).
