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).
