I think this is expected: this is really a PS/2 controller, and you can
connect either a keyboard or a mouse here.
I would then expect a pckbd to attach to pckbc1, and a pms to attach at
pckbc2. For some reason pms thinks there's nothing here.
As this is really a synaptics touchpad and not a plain PS/2 mouse
I guess the command set is a bit different. We have some synaptics
touchpad support, but maybe a newer hardware uses a different protocol.
