Then perhaps something got unset from being SUID root on my 
system during installation.  Looking at /usr/X11R6/bin/startx,
the last line exec's xinit ... ls -l /usr/X11R6/bin/xinit shows:

-rwxr-xr-x   1 root     root        10016 Feb 23 22:58 xinit

Which is clearly not SUID root... I have no reference point,
though so I don't know whether this is correct or not, and 
this may be the key to our problems.

Sure, why not?  Or then, if the *only* mouse device is /dev/sunmouse
then /dev/mouse could be the device and /dev/sunmouse can be 
skipped altogether... I'm indifferent... it's truly a matter of
preference.  I for one would probably just do the symlink method.

Also, on the topic of of which kernel to package... yeah, I'd vote
for the 2.2.5 kernel being used.  I have a happy 2.2.5 SS10:
Linux sparcy 2.2.5 #1 Mon Mar 29 01:04:53 PST 1999 sparc unknown
