Actually this is "normal" - there is one device (the keyboard controller)
but ACPI has two nodes for it. So we attach both as pckbc and then
switch the device behind it based on the port (kbd/aux).

So the question is why pms does not attach in your case, like:

pms0 at pckbc1 (aux slot)
pms0: Synaptics touchpad version 7.2
pms0: Extended W mode, Up/down buttons, Palm detect, Multi-finger Report
pckbc1: using irq 12 for aux slot
wsmouse0 at pms0 mux 0


I'd suggest to build a kernel with

	options	PMSDEBUG

and see if that outputs anything helpfull.
