podulebus —
Acorn Expansion Card bus driver
podulebus0 at root
  (NetBSD/acorn32)
The podulebus driver handles the expansion-card
  interface in Archimedes machines and their successors. This includes
  conventional expansion cards, mini expansion cards (as introduced in the
  A3000), network expansion cards (as introduced in the A3020), DEBI expansion
  cards (as introduced in the Risc PC), and Mk II network cards (also introduced
  in the Risc PC). Drivers for individual cards attach as children of the
  podulebus device.
NetBSD includes several
    machine-independent expansion card device drivers. There are also some
    device drivers which are specific to
  NetBSD/acorn32.
The following devices are supported by NetBSD.
