No smoke or flames noted. :) And that appears to have solved the
problem. Firewire audio works, and even after running NetPIPE a couple
of times over that Ethernet interface, there's only a handful of
interrupts on the Firewire IRQ (as seems to be normal):

I'll try reinstalling my other expansion cards and check that all
remains well.
Thank you very much for the help. Einfach Klasse!
