Many years ago (probably about Slackware 9.1) I used a Kensington 
trackball together with Slackware. If I remember right there was no need 
for any partikular settings for it to work.

Some less years ago (probably about Slackware 13.1) I used different 
kinds of 3DConnexion spacemouse. Those are different beasts compared to 
trackballs, but did require some extra rows in 
/etc/udev/rules.d/90-local.rules

-8<----------------------------------
# For spacemouse to work
KERNEL=="event*", MODE="0666"
# But protect the keyboard from reading
ENV{ID_CLASS}=="kbd", MODE="0640"
-8<----------------------------------

But maybe I did the settings above only to allow userspace programs run 
by ordinary users to access the device. Those spacemouse devices were not 
used to control the curson in X but to control other programs.
