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

rmmod psmouse
modprobe psmouse synaptics_intertouch=0

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

> [    3.292713] psmouse serio1: synaptics: queried max coordinates: x [..5676], y [..4732]
> [    3.340327] psmouse serio1: synaptics: queried min coordinates: x [1356..], y [1214..]
> [    3.340352] psmouse serio1: synaptics: Trying to set up SMBus access

Is there anything I have to load first, before psmouse?

HTH and regards, Daniel
