The removal of the existing keymaps from kernel depends on having an application
to be called from udev to load the proper keymaps when a device is probed.

After having it for a while, we should deprecate the in-kernel keymaps
and move them to userspace.

I also think that it is important to remove the 7 bits limitation from all drivers
and re-generate the keymaps, since they'll change after it.

cheers,
Mauro.
