For Atheros SoC = GPU + Wireless h/w.  The wireless h/w is not exposed
via PCI bus but sits on an internal bus and is controlled by the GPU
which runs a complete OS like linux or netbsd (and hopefully some day
freebsd).  The ath driver just needs the appropriate bus shim to work
and support has been available for a while.

The 5416 and 5418 are stock PCI (-express) parts that require the host
to handle much of the 11n protocol.  I've given out test hal's that
support these parts (in legacy mode) for many months.
