Hi, thanks for pointing out the problem. I tried tunning hw.psm in /boot/loader.conf by varying the values of hw.psm.synaptics_support, hw.tap_*. I always get an annoying sensitive mouse with tapping. Sometimes better, but still very annoying for typing. I would rather ignore the device if that's the only way. Also, setting these values only in /boot/loader.conf does not work. After boot it will be restored to some default values. Setting in /etc/sysctl.conf works (meaning that it really changes the parameter). Tunning by hand with sysctl also works.
