I think my touchpad is connected via I2C together with touchscreen.

Here http://www.spinics.net/lists/linux-input/msg28282.html discussion about same problem in linux
and they have a solution https://github.com/mightybigcar/synaptics-rmi4 , if I understood correctly

In OSX i2c supported, right? What do you think about that?
My laptop is not the only one in the world with this kind of touchpad, so I think many other people will certainly need a special driver for it.

I'm sure it is possible to write a driver for it. I don't know of an existing one.
 
I have never written any driver, I develop applications for iOS and OSX in Objective-C.
I think I can try to write a driver for my touchpad, but I surely need your help.
Tell me please what to begin with. Is it possible to use your code of VoodooPS2Controller for the new driver? Or should I start developing from the very beginning?

I need to create a new project in Xcode or change your?
What do I need to do for start connecting to I2C device?

An I2C driver is probably a re-write of the trackpad part. Keyboard is still handled via PS2...

I have no knowledge of I2C. I would start at the Synaptics site to see if they publish a document, and it would seem studying the Linux driver might help.
