Yes, wsmouse uses the same interface to user programs as wskbd, and
it's a series of wscons_event structures as described in

You can read directly from that wsmouse device directly, as long as
you aren't using the wscons multiplexer (wsmux); if you are, read from
/dev/wsmouse (no digit!) instead.

Nope, it doesn't. The infrastructure is there (the WSMUX_INJECTEVENT
ioctl), but nobody's bothered to write the daemon that reads from the
serial port and injects mouse events into the wsmouse stream.
