Ok, I'm not sure what's up, but it seems like for some reason, your
Open Firmware "forgot" the EDID block of this panel, it's no longer
visible in the OF device-tree. Can you try resetting the PRAM or the
power manager ?

I plan in a not so long term to add a default list of known EDID blocks
to radeonfb to work around this issue as it seems to happen on a
significant amount of these machines. Usually after a repair, but not
always.

Ben.
