Ok, I've tried both, but they both seem to have no effect on this problem.

Woohoo! Ok this is the solution! 

Now the touchpad don't get killed on starting kde. Very good job! 

Though I don't understand the difference between my previous config and your 
version -- your version works very well!

One funny detail: the horiz/vert scrolling on the touchpad-borders now work as 
well, but they did not work with my modprobe -r ... modprobe ... hack, 
allthough the touchpad itself was working -- strange.

Thanks, I'm after this problem since I have this notebook (> 2years) and 
finally I can use it without my usb-mouse ;)

But one (tiny) Problem remains: this touchpad has two vertically aligned 
buttons which work as "scrollwheel". But they don't work as expected: the 
upper one does not work at all end the lower on acts as the mid-mouse-button. 
Should I fill a new bugreport?


Best regards and thanks again

PS: I think it would be very usefull, if the above config would be automaticly 
written in xorg.conf on installing the synaptics driver. AFAIR the xorg.conf 
was not changed at all -- but at least the corepointer/coreevents-stuff has 
to be filled in in order to use a touchpad with/without mouse at all (if not 
filled in -- xorg will not start because of the missing corepointer).
