Programmatically.  The in-kernel implementation is much simpler, and
the userland code required to access it will also be simpler.
Accessing individual devices (once you know where they are) should
also be much simpler since devinfo only gives you "all or nothing".

As long as they have a device_t, it should be a piece of cake.
