Comment 62 for bug 150709

Well, if you decode that EDID as though it were legitimate (ignoring the header), then it decodes more or less legitimately. I suspect the BIOS is just doing something wrong in EDID fetch, since neither radeon nor sis will use the VBE method to get it; can you get the output of 'xrandr --prop' from this machine too, so we can see what EDID block we're actually interpreting?
