I seem to remember this discussion on the XFree mailing lists a couple of
months ago.  Apparently, the little wheel on the mouse counts as three
buttons.  ( click, roll up, roll down ).  This, when used on a three
button mouse counts as six buttons.  Apparently, the X protocol only
supports five buttons which presents some problems.

So that probably means that the little roller are buttons 3 + 4 + 5.
