scroll button on Thinkpad T40p enable

Having trouble enabling the middle scroll button (blue button) on my TP T40p.
Any advice would be welcome. Thanks

Followed these instructions:
 udev

Now that Xorg doesn't use the configuration from hal (in Debian unstable starting january 2010), the only way to “statically” configure scrolling in trackpoint is udev. (for other people, xinput method, works fine). This method will be gone (_again_) in not too long so it might be a better idea to use xinput way. YMMV.

Create the file /etc/udev/rules.d/99_trackpoint.rules as root with the following content:

ACTION!="add|change", GOTO="xorg_trackpoint_end"
KERNEL!="event*", GOTO="xorg_trackpoint_end"

ENV{ID_PATH}!="platform-i8042-serio-1", GOTO="xorg_trackpoint_end"

ENV{x11_options.EmulateWheel}="1"
ENV{x11_options.EmulateWheelButton}="2"
ENV{x11_options.XAxisMapping}="6 7"
ENV{x11_options.Emulate3Buttons}="0"

LABEL="xorg_trackpoint_end"

Save and restart udev then Xorg (or it'll be enabled at next reboot).
NOTE!
The ID_PATH used in the example above is a typical value. To determine the ID_PATH appropriate to the TrackPoint on a specific model see Determining TrackPoint Path ID

No luck. How/where do I look within the system to find the trackpad?
Thanks, Keith
