Thanks for the patch "no_dri.patch". I had the same problem as Toni Helenius before. After a few attempts to build the 2D driver with the patch, the performance is back again now. And the scrolling becomes much smoother. As the result, I have resolution 1280x1024 without sluggish movements under KDE 4. (but compiz is still disallowed)
The attachment is from my system just in case someone wonder.
