I found a "fix". Doing an
rmmod psmouse
modprobe psmouse
fixes the issue. I also tried setting synaptics_intertouch and got
this:
rmmod psmouse
modprobe psmouse

I every case the touchpad works. So there is something going wrong in
booting phase. There is says:

Is there anything I have to load first, before psmouse?
HTH and regards, Daniel
