As I said, this is the busy polling loop, quite fine from the view of KDE: 
kded *has* to do this to detect system changes because FAM isn't running.

This seems to be a configuration/installation problem of your distribution. 
Somewhere in the boot process "fam -T 0" should be started. Or add it 
yourself. For a quick test you can start "fam -d" (with debug output) in a 
shell and do "kdeinit" in another (this restarts kded).
