That quite the same as those I had in the beginning.

Well, I'm less inclined to think now that X is responsible for the high 
CPU load. I wasn't too knowledgeable about the relationships between X 
and its clients when I made my initial assumption. It was more like "I 
startx + I move mouse + CPU shoots-up => it's X".

Looks more like kde is rocking my CPU. Indeed, xev doesn't print 
anything while I'm generating high CPU with mouse movements. Also, I had 
a notion twm didn't exhibit the phenomenon as long as I didn't execute 
any kde apps. But I'm not 100% sure about the latter experiment.

I'm runing KDE 3.5.10.
