This is another example raising questions about the input system, from
the kernel to Xorg to finally reach applications.

I will write another mail about this later (maybe RFC), but it seems
that some code should be modified in the kernel and input devices
should have an input daemon outside the kernel and not in X, to easily
deal with new devices and new constraints without modifying many
layers of the whole system.

(in this case, we maybe need 2 devices because the constructor
included this as a feature, but if simple users want to add some)
