You don't have to support them, you know? It's
probably easier to only allow one device for
each irq.
I don't know, exactly, how to handle them, but the
latest linux kernels support it, which _might_
be of some use (we all know how easy to read they
are...
My guess would be that you would have to check
where the irq came from (check the device memory
space?) and from there determine which irq
to call. I don't know...
Which OS is this? Do you have a web site?
