Ok, a small udpate on my experience with ffado, the hb 12MKII and my dell inspiron 9400.

..the abridged version:

argh.. xrun xrun.. nooo xrun xrun.. remove dvd drive.. xrun xrun.. remove wireless and disable
ethernet... xrun.. try every other damn thing that people suggested.. xrun xrun..
eventually discover that i8k.ko and thermal.ko cause cpu spikes.. remove them.. oh look,
rock solid RT performance with -r 96000 -p 256 -n 2 and 6.6% reported cpu usage when idle
(no connections).

And they all skipped off into the woods to live noisily ever after.
The moral of the story.. DON'T buy an expresscard firewire interface until you have
exhausted all possibilities. Damn it. (probably wouldn't have helped anyway)

Note that I put everything back as it was. It was only the thermal and i8k (dell fan/temp) module
that seem to have caused problems. also for google reference:
pete@one:~$ lspci -nn|grep -i firewire
03:01.0 FireWire (IEEE 1394) [0c00]: Ricoh Co Ltd R5C832 IEEE 1394 Controller [1180:0832]

Incidentally, does anyone know why this thing (the phonic) has 2 firewire ports on it?

cheers,
pete.
