Looks like a touchscreen which is supported by a closed(?) source driver
of eGalax we have here too:

You can obviously download the drivers from
<http://home.eeti.com.tw/web20/TouchKitDriver/linuxDriver.htm>.

It would be great if eGalax could be convinced to get these drivers
included in main-line ;)

Hope that helps,
Niels
