This looks fine.

The other thing you'll need to do is to make the X server open
/dev/wsmouse instead of /dev/wsmouse0. It looks like "/dev/wsmouse%d"
is hard-coded into Xmacppc; you could patch and rebuild Xmacppc
(around line 230 of
xsrc/xc/programs/Xserver/hw/netbsd/macppc/macppcInit.c), or cheat by
moving the real /dev/wsmouse0 aside and making /dev/wsmouse0 a symlink
to /dev/wsmouse.

(Besides making X work with multiple mice, using the wsmux device has
the fringe benefit of making X start happily *before* a mouse is
connected at all, which is good for detachable USB mice, or for
systems with no mouse or keyboard where you just want to use x2x).
