Mapping unused Touch Screen Area to Soft Buttons / Commands

Hello,

I've got a resistive touch screen, where the touch area is larger than the display area. I'd like to map "soft buttons" (e.g. ESC or num block ENTER) to the area outside of the screen -- similar to androids [BACK], [HOME], [MENU] buttons at the bottom.
On the linux-side, the device is handled by AD7879-i2c driver -> /dev/input/mouse0. Using xinput_calibrator (creating some X rules), I can calibrate the mouse to the "display" area.

The two main questions are:
* can xorg (or modules / w/e) still see the absolute coordinates, that are outside of the screen? (Compare to "a window that's just outside of the screen is not clickable")
* is there a module that can map virtual hardware buttons to mouse-click-locations?

I'd love to do it in X because the calibration process using X and xinput(_calibrator) is very straight forward for the user.

so long..
Andy

Any pointers?

Ad. question 1: what is the command line to display ("debug") the (transformed) mouse events?
Ad. question 2: what's the best place to ask?

so long..
