eGalax touchscreen driver

[Andrew Wood <a.j.w@me.com>]

Is there a Debian package which provides a driver for eGalax touchscreen 
controllers? The driver is available from the manufactuer here
http://home.eeti.com.tw/web20/eGalaxTouchDriver/linuxDriver.htm

but Im concerned that if I install that I will have problems with future 
kernel updates.  Is there an official Debian package which provides this 
or an equivalent driver?

Thanks
