I admit I quite like this solution. It would also help displaying
something sane (blank, pattern, whatever) on screen during driver
teardown instead of the junk left by X...

I'll look into including that switch into my pmac code as well
and see if it works properly in all cases (I think so). Also,
recent DRI CVS finally has working suspend/resume (works on
console switch too).
