My idea was, to have a state automata for LK501 by extending existing
dev/dec/lk201_ws.c, not to generate LK201/VSXXX-GA byte stream to feed
them upper layer by making 'dtop' a serial chip masquerade.  Runtime
keyboard layout identification would be a cool feature.  (Hi, Matthias,
I will send you the proposed design of lkkbd_softc/vsxxx_softc.)
