I think it shouldn't even work, if linux uses devkit or HAL, but I also
added the following to /etc/hal/fdi/policy/trackpoint.fdi:

<?xml version="1.0" encoding="utf-8"?>
<deviceinfo version="0.2">

    <!-- Trackpoint -->
    <match key="input.product" string="TPPS/2 IBM TrackPoint"> 
       <merge key="input.x11_options.EmulateWheel" type="string">true</merge> 
       <merge key="input.x11_options.EmulateWheelButton" type="string">2</merge> 
       <merge key="input.x11_options.EmulateWheelTimeout" type="string">200</merge> 
       <merge key="input.x11_options.YAxisMapping" type="string">4 5</merge>
       <merge key="input.x11_options.XAxisMapping" type="string">6 7</merge>
