tslib lives here:
http://tslib.berlios.de/

The readme is here:
http://svn.berlios.de/viewcvs/tslib/trunk/tslib/README?view=markup

The documentation is almost non existent, but there are examples and the source is of coarse, readable.

Written properly, a Qt application for touchscreens can be used with any device. The touch screen is
basically used as a mouse, so it doesn't matter to an application whether Qt is using tslib, the
Linux touchpad driver, or desktop mouse.

Not quite sure what Qt for S60 will use for touchscreen back-end, but an average application won't
need to care.

Qt Embedded started in the Qt 2.2 series, so it has been many years since Qt has had touchscreen
support.
