FWIW: I installed the 4.0 (not even 4.0.1) XFree86 binaries last August on
NetBSD 1.5_ALPHA.  wsmouse support was present back then (even before
Fredereick Bruckman's cited 4.0.1).

What was missing was autoconfiguration support for wsmouse.  But I've
tramped through the XFree86 config files a few times (not extensively; I'm
by no means an expert; (^&).  Manually setting it to use wsmouse was
straightforward, and worked nicely.

It would be nice if autoconfiguration would find the wsmouse interface, if
present.
