[Arm-netbook] Interfacing touch screen to EOMA68-A20

Hi,

I got me 5 pieces of 4.3" touch screens. It should be same as the lcd described here that is already working:

It has something extra - 4 wires for a touch interface - resistive.

The signal pins are marked: 37 XR Touch panel XR 38 YD Touch panelYD 39 XL Touch panel XL 40 YU Touch panel YU

They were purchased from Aliexpress - (cheaper when I bought it). http://www.aliexpress.com/item/4-3-inch-KD43G18-40NB-A1-KD43G18-A5-4-3-C430P...

Any ideas which cheapie chips best to use with EOMA68-A20 to get touch screen operational?

I assume it has to be I2C and somehow a bit of driver software will run and convert the I2C signals to mouse movements.

Any pointers appreciated.
