I'm interested in helping out there. I haven't had time to draft
a driver API proposal that I discussed with Keith last week though
but what you are doing may just fit well in that direction.

We should though separate, I think, the monitor detect & mode setting
code from the 2D accel. And we need to figure out a good way to
arbitrate the HW access between all those entities (2D accel, 3D pipe
and mode changes/updates).
