I recently switched to using evdev and when I removed the InputDevice sections
from xorg.conf I had to add an fdi file to /etc/hal/fdi/policy (which I cleverly
named 10-x11-logitech.fdi) containing this:

<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
   <device>
     <match key="info.product" contains="ImExPS/2">
       <merge key="input.x11_options.EmulateWheel" type="string">true</merge>
       <merge key="input.x11_options.EmulateWheelButton" type="string">8</merge>
     </match>
   </device>
</deviceinfo>

I constructed that file by looking at mouse-oriented parts of the output of
'lshal' and just stuck the options in where it looked reasonable.

It worked, and I'm still amazed.
