Yes, definitely works on Qtopia too.
The only users of the touchpad are the core Qtopia libraries, and
hald-addon-keyboard.
Qtopia doesn't seem to care.
hald-addon-keyboard does test for BTN_TOUCH at one point, and if it is
available it sets the "input.tablet" capability.
I don't really know how that is used, but it doesn't seem to affect
anything.

However I have discovered that "neod" has
 #define TOUCHSCREEN_BUTTON_KEYCODE 0x14a

and 0x14a is BTN_TOUCH.  neod beeps for you whenever it gets this
keycode. 
So that would need to be fixed to respond to either BTN_TOUCH or
BTN_STYLUS.
Ideally it should probably beep on any button from BTN_MISC up to 
 KEY_OK - 1

This is turning out to be slightly more awkward than I hoped, but I
still think it is the right direction.

Obviously the kernel list isn't the place to be talking about
modifying neod (and tslib).  Would "devel at ..." be the right place or
is there somewhere better?
