I don't know how to put it in correctly right now. There isn't a working way to represent multiple busses from a single device in the dts. Since I can't test the 8151 (free version of SimNow), this is as complete as I can make it.

The register in the routing table gets set up correctly. I didn't have to mess with that to get it exactly the same as v2. Thanks, Myles
