Which driver for Elo touchscreen and recent versions of Xorg?

[Javi]

Hi,

I'm in the process of migrating 200 game computers from Windows to
Linux. Most of them have an Elo TouchSystems Touchscreen  as input
device. After some research I have found two compatible drivers: the
proprietary one (http://www.elotouch.com/Support/Downloads/dnld.asp)
and the open source evtouch, but none of them are compatible with
Xserver 1.5 or later.

I plan to use X Server >=1.7.6 so ... is there any alternative driver
available for such touchscreens in recent versions of Xorg?

Thanks
