Thinkpad X230 with VoodooPS2Controller and Synaptics

Hi, I would like to work around with VoodooPS2Controller source code, because I've the touchpad with 2 clicks working, but there are 2 separate clicks and a trackball attached to the keyboard that are not working.
Can you give me some directions to start modify VoodooPS2Controller source code ?
Here are my Clover and ioreg.
Thanks.

BTW, I've noticed a KBD and a MOU devices in ioreg.
