You might ant to look over there. I would rather attribute this symptom to a problem in X, where the X server is allowed to monopolize much of the machine for redrawing. The fact the our current X servers (all those I tried, even Xpmac_mga accelerated for my Matrox) eat _huge_ amounts of CPU for all blitting operations like scrolling etc. There seems to be work to do on the X side of things....
