Zaurus has two microswitches, indicating one of 3 configurations:

notebook, closed

notebook, open

tablet

They are exported as event/switch in the input. If possible, it would
be nice to have one interface for that, too. (And it probably should
be input,  and not fake-accelerator based; after all, there are no
accelerometers on zaurus-like systems).
