Thanks for the files, I don't see any obvious reason for the failure
yet, but still think that it may be a kernel problem.
Since ACPI and (L)APIC seem to be handled the same way, it could be a
bug in the ohci1394 module iself. Do you know if your firewire port
works with other linux distributions using the same kernel?
The boot option
knoppix acpi=force
for forcing interrupt detection & handling via ACPI could maybe be worth
a try.
