how to read absolute positions of tap from Cirque touchpad in linux

we have one of Cirque touchpads. http://www.cirque.com/downloads/docs/tsm9925.pdf

now we want to read absolute position of tap from this touchpad using c\c++ application. unfortunately company developed only windows drivers but we need to read positions in the linux. we tried to use /dev/input/eventN subsystem but received only direction of finger moving and speed of finger moving.

is it possible and how can we do this?

Solution

From your supplied link:

For custom functionality at the product design stage, we offer software that 
allows OEMs to enable, disable or personalize advanced settings and/or 
reprogram the touch sensitive area.

I'd suggest contacting Cirque directly
