Okay - got libiec61883 downloaded and built. test-plugs reports
absolutely nothing. It just sits there until I Ctrl-C it, then it
reports "done".

plugreport reports:

Incidentally, lspci reports the following for the firewire card:

(prog-if 10 [OHCI])
        Subsystem: Unknown device 8919:0400
        Flags: bus master, medium devsel, latency 64, IRQ 10
        Memory at dfeff000 (32-bit, non-prefetchable) [size=4K]
        Capabilities: [44] Power Management version 2

I do, but I'd have to find the right cable. The second box would have
to be a Sony VAIO, and I can't find my 4-pin to 6-pin firewire cable at
the moment!
