I'd be interested in checking if your EDID has somehow been corrupted.
The LP2480zx has a feature where it can update the EDID with the
correct colorspace co-ordinates depending on the chosen colorspace. It
would appear if you turn this feature off (to never change the EDID
even if you change the 3d lut) the EDID checksum is incorrect.
I'm pretty sure this EDID updating feature is turned on by default,
although it's kinda hard to turn on if you ever turned it off, as the
OSD for this feature is only available if you have a valid input,
which in the case of the new drm, you won't.
a comment on dynamic EDID handling:
Some devices need a firmware update. I checked on osX which handles
dynamic EDIDs fine. Nouveau on Fedora13 and the nvidia driver
openSUSE-11.2 fail to update the EDID info. The X server needs to be
restarted before the changed EDID becomes visible.
kind regards
