I have a horizontal wheel on a Logitech mouse. I use the evdev driver
in xorg.conf, and everything works great. The only thing I had to do
was change so that pressing the button left vs. right generated the
correct event.

Section "InputDevice"
        Identifier  "Logitech Optical Mouse"
        Driver      "evdev"
        Option      "Name" "Logitech USB-PS/2 Optical Mouse"
        Option      "HWHEELRelativeAxisButtons" "7 6"
