disabling synaptics touchpad on hp ze4500
 

Can anyone help me with disabling the touchpad on my hp laptop while using Suse? I use a wheel mouse for input, and typing is disrupted with the touchpad on. I tried disabling through the BIOS, with no luck.
Portions of my Xorg.config is below.

Thanks,
Ouzo
