OK, so I tried, and what can I deduce from this: I configured fwe0 on 
both and pinged from A to B, no response was received:

B crashed (ok, so I assume this means it doesn't work). Interestingly, 
this one has a Ricoh R5C552 chipset which should be supported. But, it 
could be a conflict on the PCI-Cardbus bridge with the same IRQ?

On A, this output appeared in dmesg:

fwohci0: BUS reset
fwohci0: node_id=0xc000ffc1, gen=3, CYCLEMASTER mode
firewire0: 2 nodes, maxhop <= 1, cable IRM = 1 (me)
firewire0: bus manager 1 (me)
fwohci0: BUS reset
fwohci0: node_id=0x8000ffc0, gen=4, non CYCLEMASTER mode
firewire0: 2 nodes, maxhop <= 1, cable IRM = 1
firewire0: bus manager 1
firewire0: New S400 device ID:00e0180003094339
fwohci0: BUS reset
fwohci0: node_id=0xc000ffc0, gen=5, CYCLEMASTER mode
firewire0: 1 nodes, maxhop <= 0, cable IRM = 0 (me)
firewire0: bus manager 0 (me)

Does this mean it works? (the last 4 lines appeared after the other 
machine crashed).

The interesting thing is that this one has a Texas Instruments PCI7x20 
1394a-2000 OHCI Two-Port PHY/Link-Layer Controller, attached to a Texas 
Instruments PCI7420 FireWire + CardBuss bridge. None are on the hardware 
list (R6.1).

The bridge also have a Texas Instruments "PCI7420/PCI7620 Dual Socket 
CardBus and Smart Card Cont. w/ 1394a-2000 OHCI Two-Port PHY/Link-Layer 
Cont. and SD/MS-Pro Sockets" attached which doesn't work.

I'd be happy if things work on A, as this is my new machine :)

Thanks, Erik
