The current recommendation is to use the uart(4) driver, which should
support the same chips as the zs and sab drivers (unless you're on an
Enterprise 00). The tty device changes to /dev/ttyu*.
Prior to that change I had gettys starting on ttyz and not using the
ttya/b links -- I'm not even sure where those come from.
