Attached :-) I'm assuming you use the logitech busmouse driver. Logitech
makes many kinds of mice.

This is a kernel driver so it is independent of XFree86. Use the
configuration I told you about with X and it will work. Well as long as
XFree86 doesn't break its PS/2 driver.
If you have any problems setting it up let me know.
MS: (n) 1. A debilitating and surprisingly widespread affliction that
renders the sufferer barely able to perform the simplest task. 2. A disease.
