Touchscreens (was: Touchsmart touchscreen all-in-one desktop computer $699)

[Tyler Aviss]

I'd be happy to find LCD touchscreen stuff that I know would work with 'nix.

I have a 7" Lilliput that *used* to work years ago when I had a 2.4
kernel with X11 (Debian). It had a driver which I had to compile, but
other than editing a source file to swap the X&Y it worked great.

Now I've got a newer kernel and X.org, and with the eGalax driver, and
the darn thing will NOT calibrate properly. I've manually entered
values, tried using "evtouch" with the configurator, etc etc. No luck.
Usually it starts OK at the top and then by about halfway down the
cursor is off in la-la-land.

Anyone know what touchscreen drivers exist that don't suck (other
than, assumedly, WACOM, of course... and even those seem touchy at
times)?
