What's the status of the problem with 2 devices (rt + non rt) sharing the same interrupt? It's possible that there is still a problem with IRQ sharing. I think Jan can say sth to this issue.
Yes, sharing IRQs between RT and NRT devices will not work (in theory, this is possible but it would require a - not yet existent - patch of the NRT driver of your card). We faced the same issue on our embedded systems, and the only solution was to reserve an exclusive IRQ for the RT adapter (in our case by setting some jumpers).
