You are right, but I didn't know really what could influence the load of X. I 
have kde runnning (3.5.8), with kmail, no 3d-applications or compiz (only 
some transparency for menus in kde), a konsole for top, X 7.3; intel driver 
from git.

Ok, I don't know if I use it the same way as you, but your comment made me 
think, that the behaviour might be quite normal. I can see for example, that 
the fact that I'm writing these lines brings X from around 10 % up to 20-30%. 
Same for every change of the all application-windows (moving them around and 
changing the contents). Also if I open a konqueror window and move it around 
fast, X goes up to 80%.
