Yes and I've given you examples later in the same email. The main one
being that early resume console thing. And yes, I did it in an arch
specific way, because there was no way I could resume the display _that_
early in a general case, and yes, I think it might be interesting to
think about doing the general case still (though the main problem will
be the resuming of AGP which currently
tends to not follow any correct ordering rule vs. the video chip on the
bus).
