This can also be configured in the X server with 'xmodmap -e "pointer
= 1 2 3 6 7 5"' or something like that. Maybe XF86Config should be
extended to take a line of that form, instead of the current and more
restrictive 'ZAxisMapping' line.

Having the number of buttons fixed, or the number of scrollwheels is
flawed, IMHO. My mouse (A4 Tech) has two mouse wheels and only 3
buttons, for example.

But I will look into Gdk 2.0.0 and resubmit my renewed patch, as soon
as I find time.
