Greg?

I know you alluded to going your own way if the auxiliary bus patches
did not shape up soon, but it seems they have and the stakeholders
have reached this consensus point.

give the final set another once over, but David has been diligently
fixing up all the declared major issues so I expect to find at most
minor incremental fixups.
