Any kind of buttons that are not keys in the traditional sense: mouse
buttons, gpio buttons, power buttons, CD eject buttons, etc.

In theory also other stuff like relative movements (mouse, joystick),
absolute movements (touch pad, pen) and maybe more. But I don't see what
lcdproc would do with them, so right now these are entirely ignored.
I guess one could merge the existing joystick driver into this one, if
anybody cares enough to do the work.

My use case is the gpio-keys kernel module. With that one I can actually
use standard keycodes (if they don't interfere with the rest of the
system - haven't tested yet), but it is still useful to get input from
the kernel without a controlling terminal.

best regards,
