Well, synaptics is not working for me at all (Dell XPS 13 Skylake). It 
loads, but produces a lot of spam in xorg log, mouse jumping randomly. 
It works as sysmouse. So, I think yes, Xorg or FreeBSD has something 
fishy with synaptics. Personally, I'm waiting for evdev or libinput 
support, so I disabled touchpad.
