If it's a standard scroll-wheel compatible button or pad, you can try this
in your /etc/X11/XF86Config:

Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "mouse"
        Option      "Protocol" "wsmouse"
        Option      "Device" "/dev/wsmouse"
        Option      "Buttons" "5"
        Option      "Emulate3Buttons"
        Option      "ZAxisMapping" "4 5"
EndSection

Note the "Buttons", "Emulate3Buttons" and "ZAxisMapping" options.  That
should at least do the up/down part.  You might need to tweak it for
left/right.  The XFree documention may provide more information (try
google).
