A ``PS/2 to serial adaptor'' must be something with a fair amount of
logic on it, not just a simple two-connector-with-some-wires gadget.

If it's the latter, your mouse ain't PS/2, it's just a serial mouse
with a Mini-DIN connector.  This one is _not_ covered by the psm
driver.  The true PS/2 mouse is perhaps better described as ``keyboard
mouse'' (other unices include them into their `kd' driver).  It plugs
into the keyboard controller and acts very similar to a second
keyboard, just that it sends mouse events as opposed to scan codes.
