Stuff is figured out itself now anyway. :-S

You have hal-0.5.10 installed and compiled xorg-server with hal. Now hal will 
scan the attached devices and hotplug available mice. The touchpad is 
recognized as a mouse and the "evdev" driver is loaded with uses absolute 
mode since the device emits absolute coordinates. 
These devices are even added when you already have a mouse input device in the 
xorg.conf, thus giving you a lot of mice that use the same data (some guys 
report double clicks on single clicks, keymaps changed, the touchpad does not 
work right anymore). 

Put
	Option "AutoAddDevices" "false"
in the Section Serverflags and xorg will stop to hotplug mice. 
Or add a custom policy file in /etc/hal/fdi/policy/ to add the touchpad with 
the synaptics driver instead of evdev.
