KDE Slimbook and its Synaptics-less Touchpad

Hey Plasma,
One of the things that could be improved in the KDE Slimbook is that
since the touchpad is not synaptics-based the kcm is entirely
disabled.

Nevertheless, Alejandro recently pointed out to me that XInput is
still providing some options that could be useful to our users and
maybe it could make sense to show these when full synaptics support
isn't available.

Is there anyone who could spend some time to look into the issue?

Below is the xinput output.

Thanks!
Aleix
