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

>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.
