Steven,
I do not know details of the architecture you are trying to build,
but have you thought about pseudo driver layered on top of the
existing PCI leaf drivers, rather than nexus beneath them (so to speak) ?
It could be task easier to accomplish, than building the nexus. It also
will have a nice side effect of being DDI compliant (which nexus would not).
