Can you nuke just the intel_mark_busy side? Keeping the mode finder
intact would be useful as the intrepid reader need only then implement
the intel_frontbuffer callbacks and have the harder part of matching
appropriate modes and switching routines ready to plug in. (Those latter
ones I expect to be tweaked over time, and so the reader's first step of
reverting this commit would conflict in such a way as to dissuade them.)
