err, what URL are you a talking about exactly?

Ok...

the NetBSD/Amiga "zbus" configuration driver uses kind of a virtual Zorro bus,
defined by the device list maintained by the expansion.library.

On real Amiga machines, it contains, (mostly: some vendors are cheating)
AutoConfig (tm) devices on the Zorro (II or III) bus.

On DraCo machines, it contains AutoConfig (tm) devices on the Zorro II bus
and DraCo local bus devices. The DraCo local bus is, as I understand, a 
buffered 68040 bus, with some additional logic to feed the expansion.library
list. NetBSD contains currently exactly one driver for such a device (the
Altais == Retina-Z3-on-DraCo), but there is also the DraCoMotion (Video/Audio
grabber/player board, kind of next version of a VLab Motion + Toccata 
combination).
