Meanwhile, the cause of the problem is known. It is due to
- a multiboot setup,
- the fact that Synaptics mode settings aren't completely reinitialized
after a warm reboot, and
- a shortcoming of pms(4), which doesn't recognize the "capabilities" of
this touchpad model properly.
After a reboot from another OS into OpenBSD, the touchpad may run in the
so-called "advanced gesture mode" and send packets which are not expected, and
misinterpreted by pms. A patch is being prepared.
