--- Comment #1 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Probably missing some initialization. Can you boot with 'nouveau.debug=debug'
(which turns on all nv_debug messages) -- there's some stuff in DP init that
might make sense to someone. [Unfortunately I know very little about DP.]

If you'd like to push this further yourself, you could make an mmiotrace of the
blob of a unplug/plug sequence, that might give someone some hints. See
https://wiki.ubuntu.com/X/MMIOTracing for some hints as to how to start.
