IMHO, on any system where pckbc0 is configured, it should always be attached
(and just disable itself, polling for validity every now and then, if
invalid spew on the port is seen).  There's precious little that abuses the
IO port and IRQ of the keyboard controller, so I don't see attaching all the
time as a problem.  It'll go onto the wsmux and will propagate no events,
thus doing nothing harmful.

I think the only oddity mentioned about this before is that probing is a
little strange if there's no keyboard attached.  Perhaps only real testing
can show if it'd be a problem to attach the device always.
