disabling touchpad on notebook

[Darrell Esau]

Hello all,

I have a Dell Inspiron 4000 laptop running FC3.  I'd like to disable the 
touchpad and use only a microsoft USB wheelmouse.  

Currently when I plug the USB mouse in, it works fine, however the touchpad is 
also working.

Does anyone know what to do with the xorg.conf to disable the touchpad?

Below are what I believe to be the relevant sections of the xorg.conf file:

Thanks,
d
