Thefwohci device driver first appeared in
  FreeBSD 5.0. It was added to NetBSD
  4.0.
The fwohci device driver was written by
  Katsushi Kobayashi and Hidetoshi
  Shimokawa. It was added to NetBSD 4.0 by
  KIYOHARA Takashi.
The driver allows physical access from any node on the bus by default. This
  means that any devices on the bus can read and modify any memory space which
  can be accessed by an IEEE 1394 OHCI chip. It is allowed mostly for
  sbp(4) devices. This should be
  changed to allow it only for specific devices. Anyway, IEEE1394 is a bus and
  not expected to be connected with un-trustable devices because a node can
  monitor all the traffic.
