AFAIR (it's now nearly ten years since I worked in this area), it
simply opens /dev/mouse and select()s on and read()s from it.

The configuration file for the mouse with Xsun is called sunMouse.c
and is located somewhere below $X11R6_BASE/xc/programs/Xserver. ;-)

I ported the X11R5 MIT server to an OS-9/68000 box using a Microsoft
compatible serial mouse for my diploma thesis. Drop me a note and I'll
try to dig out the *Mouse.c I wrote then. It should work for X11R6 on
SPARC with some easy work (mostly device special file name, serial
port ioctls and such things).

Should somebody want to publish this or to put it into mainline BSD
src-es or pkgsrc-es, I would think it advisable to ask the Universität
Karlsruhe for permission.
