I fetched xinput from Debian jessie armel:

xinput --list --long
⎡ Virtual core pointer                          id=2    [master pointer  (3)] {snip}

        Reporting 4 classes:

⎣ Virtual core keyboard                         id=3    [master keyboard (2)] {snip}
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)] {snip}

And with

xinput set-prop 'multitouch' 'Multitouch Device Orientation' 1

one can rotate the input device.

A better way to restart X (without the need to modify makexconfig) is still needed to create an easy to use Kual package.
