First, thanks for the VC definition.

Based on that bit of info above, wouldn't it make sense to use the:

Option "UseEDID" "FALSE"

Most likely, although getting any random mode to work on a DFP seems
rather unlikely.


and in the xorg.conf and manually input the needed settings?  I also would
consider adding:

Option "UseDisplayDevice" "DFP" just to be sure.  I believe that is what I
had to do a few years back when my nvidia card insisted on using only the
analog output.

From the X log, its already using the DFP, its just that its not going
with a valid native mode, since the EDID seems to be borked.  What
would be most useful right now is to start X with the following
command:
startx -- -logverbose 5

and then send the resulting X log so that we can see what's actually
in the EDID.
