+<p class="Pp">The driver allows physical access from any nodes 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 <a class="Xr">sbp(4)</a> devices. This should be changed to allow
+ it only for specific devices. Anyway, FireWire is a bus and not expected to
+ be connected with un-trustable devices because a node can monitor all the
+ traffic.</p>
