The current ppbus code layers so :

	+--------------+---------+-----+------+
	| ppa3/vp0/Zip | new_lpt | ppi |  ??  |
	+--------------+---------+-----+------+
	|        ppbus primitives             |
	+--------------------+----------------+
	| ppc (ISA chipsets) |        ?       |
	+--------------------+----------------+

ppc	ISA parallel port access code	(works, need more chipset support)
ppbus	Bus code			(works)
ppa3	Parallel Zip driver		(works)
new_lpt	Traditional printer driver	(works, polled mode only)
ppi	User-space parallel port access	(under development)

Notably, there is no 'lp' replacement yet.  The new code will coexist
(but not share ports) with the old 'lpt' driver, so I think it's time
to give it some wider exposure, particularly if this shakes any more
bugs (or developers) out.
