When I say "X feels jerky", I mean that I can notice the scheduler is
not giving the X server enough CPU cycles (I mean, a continuous,
smaller, but more frequent CPU timeslice) to perform window movement and
redrawing fast enough to get ~25fps. Also, I don't think it's related to
the video card. The combo patch I did with Mike's + Ingo's enhacements
works beautifully for me.
