Emulating 3 buttons on a 2 button mouse

[Jesse Wilson]

In your /etc/X11/XF86Config file:

Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "mouse"
        Option      "Protocol" "PS/2"
        Option      "Device" "/dev/psaux"
        Option      "ZAxisMapping" "4 5"
        Option      "Emulate3Buttons" "yes"
EndSection

That last option should enable emulation...
