any way to _really_ disable "autorun server". and 100% cpu problem

No matter how I try I have "KDE Autorun Server" start on KDE startup 
always. I have it disabled, but nevertheless even if I click the icon 
in the tray and hit quit it would exit, but would load again next 
time. It also seems to be accessing disk every second or maybe even 
more often (at least led blinks), since this is a laptop I am afraid 
it may cause higher power consumption.

Another problem I am seeing ever since I upgraded to orth packages and 
now with as packages cpu consumption sometimes goes to almost 100% 
(they are consumed by the following three processes:

kdeinit: kded
kdeinit: kwin -session 117f0000010001044487747000000

and 

/usr/X11R6/bin/X :0 -dpi 100 -nolisten tcp vt7 -auth

once this starts the only way to stop it seems to be restarting KDE. 
It also appears that this happens more with 2.4 kernel than with 2.6 
(but I am not sure there is a link)

Any ideas on what can be done?
