Is there command space left in FIFO_TOUCH?
Its bit space usage isn't documented in
like sound and wifi are, for example.
Could we at the same time document the format of FIFO_TOUCH
in that header?
(I've got no time to look at how FIFO_TOUCH is processed
in detail atm, sorry if what I'm saying is bogus.)

Back light control would be nice indeed.
Much more useful than temperature.
It would also be great if we could suspend when the lid is closed
some day, I guess FIFO_POWER might also be useful for that?
