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.
