You typically need to set up quite a bit of the PCI subsystem for it to work -- including not only bridges and devices on the path to the PCI function you're interested in, but also any siblings of any such.
Why would that be?
And you need to do some work with the north bridge typically (open up some window there).
thanks for the compat chain that we reliably have on x86, all of the above is a noop on 100% of our currently supported machines.
If we happen to see a system where this actually matters, we can still decide not to go ehci if we find a simpler solution, but lets not talk this dead for no realworld reason now.
