	When hacking on an sfb X server for alpha, I discovered that the
	zs keyboard is not actually initialized the way it's supposed to be
	in lk201_init, at boot time...because lk201_init is called before
	the serial baud rate is set.
	Read data from the keyboard, note that the keys only ever generate
	KEY_DOWN events.  Unplug the keyboard, plug it back in, lk201_init
	gets rerun, and viola! the keyboard works properly.

	(If you want the actual test code, preliminary diffs to the sfb
	driver and Xserver are at
