Scroll wheel on IBM/Lenovo Thinkpads

One thing that I've missed on my otherwise near perfect x60s is a scroll wheel. Some days ago I came across a cool hack that let's you have just that!

In your xorg.conf just add the following to the mouse InputDevice section:

Option "EmulateWheel" "on"
Option "EmulateWheelTimeOut" "200"
Option "EmulateWheelButton" "2"

Thanks to Skip Paul for initially blogging about it here.
