Ok, patch looks sane, but it does leave me with the "what about the
'fb_changed' case?" question. Is that case basically guaranteed to not

None of the existing drivers turn anything on or off in the
mode_set_base code; the fix I intended was purely for the mode_set case,
which always turns on all of the connected outputs. I just screwed up
and stuck it in the wrong place.
