 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.
