Thanks I will try that. But typing

   hermes:/home/doug# sysctl hw.psm.synaptics_support="1"
   sysctl: unknown oid 'hw.psm.synaptics_support'

I assumed I would get the same result from loader.conf. I can try loading the 
synaptics driver, but in the meantime what I did works

Note xinput list gets:

  Virtual core pointer                id=2    [master pointer  (3)]
     Virtual core XTEST pointer       id=4    [slave  pointer  (2)]
     sysmouse                         id=7    [slave  pointer  (2)]
     Mouse                            id=8    [slave  pointer  (2)]
  Virtual core keyboard               id=3    [master keyboard (2)]
      Virtual core XTEST keyboard     id=5    [slave  keyboard (3)]
      kbdmux                          id=6    [slave  keyboard (3)]

I have moused_port="/dev/ums0" in rc.conf. In any case id=7 is my usb mouse 
(working fine) and I can type because id=8 (the touchpad) is off. Also fine :) 
Between the physical dimensions of my laptop and the way I hold my hands, 
typing was impossible.
