Using more than 5 buttons in XFree86

[Ray Lai <raylai@mailandnews.com>]

I did a lot of digging through mailing lists and stuff but I haven't found any
official documents stating that there is a maximum of 5 mouse buttons avaiable
in XFree86.  I have a Logitech Optical Mouseman Wheel and it has two buttons on
the top, a mouse wheel which is also a button, and a thumb button, making that
a total of 6 buttons, including scroll-up and scroll-down on the mouse wheel.
I would like to use all 6 buttons if possible, has anyone gotten it to work in
XFree86 3.3.6?
