Well, as it seems, the problem was/is not that simple. After having changed my harddrives to use dma (yes i double checked them all) I still get the lagging mouse etc. if i put some load on my system. E.g. if i compile something in a terminal in kde, then my load goes up to 2.5 (is this unusually high ?), and my mouse starts only getting updated 2 times/sec, same is with keyboard input. With SuSE i never ever got a laggy mouse (ok, maybe with load 10 or something).
