Middle Click Scrolling with Lenovo TrackPoint

I just found this handy script when I got my new Lenovo X220 Tablet with a TrackPoint.  I couldn't get the middle click to work correctly with it; it was configured to be a middle click button (which makes perfect sense) but I wanted it to have scrolling capabilities.
You just add this to /etc/gdm/PostLogin/Default and give it executable rights.

#!/bin/sh

xinput list | sed -ne 's/^[^ ][^V].*id=\([0-9]*\).*/\1/p' | while read id
do
        case `xinput list-props $id` in
        *"Middle Button Emulation"*)
                xinput set-int-prop $id "Evdev Wheel Emulation" 8 1
                xinput set-int-prop $id "Evdev Wheel Emulation Button" 8 2
                xinput set-int-prop $id "Evdev Wheel Emulation Timeout" 8 200
                xinput set-int-prop $id "Evdev Wheel Emulation Axes" 8 6 7 4 5
                xinput set-int-prop $id "Evdev Middle Button Emulation" 8 0
                ;;
        esac
done


# disable middle button
xmodmap -e "pointer = 1 9 3 4 5 6 7 8 2"
