So you have a usb keyboard and it does not work for you?
Comment out the following lines:

#pckbc*          at acpi?                # PC keyboard controller
#pckbc0          at isa?                 # pc keyboard controller
#pckbd*          at pckbc?               # PC keyboard
#pms*            at pckbc?               # PS/2 mouse for wsmouse  
#wskbd*          at pckbd? console ?     
#wsmouse*        at pms? mux 0

And try again...
