It used to be confiugred in xorg.conf:

Section "InputDevice"
        Identifier      "Configured Mouse"
        Driver          "mouse"
        Option          "CorePointer"
        Option          "Device"                "/dev/input/mice"
        Option          "Protocol"              "ImPS/2"
        Option          "Emulate3Buttons"       "true"
EndSection

You could put something loike that (most likely you dont' have a PS/2 mouse :-)
into /usr/share/X11/xorg.conf.d/my-mouse.conf
