Thats actually a super interesting question and something that should not be impossible to work out. The touchscreen is connected to the mobo with a 4 pin connector. I don't see an IC on it so I assume it must be analogue signals coming out. I might see if I can work out the way to read data off it and see if there is an observable difference for multitouch
