It seems like every new release breaks my old method of doing things. I've had to revisit and edit this topic a number of times. This time I feel I've almost gone round circle with an xorg configuration file. Credit goes to sillav

I repost sillav's solution (with a minor edit) as I feel this topic deserves its own thread.
Create the following file as root:
Put the following content in that file:
Identifier "Trackpoint Wheel Emulation"
MatchProduct "TPPS/2 IBM TrackPoint|DualPoint Stick|Synaptics Inc. Composite TouchPad / TrackPoint|ThinkPad USB Keyboard with TrackPoint|USB Trackpoint pointing device|Composite TouchPad / TrackPoint"
Option "EmulateWheel" "true"
Option "EmulateWheelButton" "2"
Option "Emulate3Buttons" "false"
Option "XAxisMapping" "6 7"
Option "YAxisMapping" "4 5"
This is also posted down the list of possible solutions at www.thinkwiki.org
(I was using the xinput method in F16, but cannot get that method to autostart in F17).
