I assume there's a monitor actually connected (that supports EDID)? Did this
work with older kernels (if so which)?

Please upload a copy of your VBIOS (/sys/kernel/debug/dri/0/vbios.rom)

It is fairly old machine and before I installed Fedora on that it was
virus-infested Windows XP which apparently supplies better default EDID data in
case something goes wrong...
