Subject: add support for devices on the SSB bus

This provides detection of e. g. Broadcom wifi (b43) or ethernet (b44) devices.

This doesn't update the spec for the new bus, but has been used successfully
for years, and other buses were recently committed without spec updates as
well. With hal being phased out and in maintenance mode, that should be
appropriate now.

See thread at http://lists.freedesktop.org/archives/hal/2007-April/008080.html
