XFree has some support for various touchscreens:

You may also want to look at Metro-X from a former company I worked with (
http://www.metrolink.com). It's no longer supported, but has support for a
variety of touchscreens.

You can make it work. One trick is to keep as much mount read-only as
possible. You'll need some writable space, but you can use RAM or a
partitiion if needed.
