evdev is put forward as standard example because - unlike most other drivers -
most of its code deals with being an X driver, not a hardware driver.  There's
little protocol crazyness, only few ifdefs, and the code is relatively
straightforward.

I'm sorry if you don't see how that is a good way of _learning_ how to write
an input driver.
