OK, so after swapping out my soundcard for an old soundblaster Live!, I
can run jack and Ardour with the alsa driver. But that's not the way to
do real work. My testing was interrupted by real life, and the need to
purchase a 6pin - 6pin firewire cable, so that I could plug my saffire
interface into the desktop.
Finally getting back to it today, and of course, it doesn't 'just work'.
Jack aborts soon after starting, with a 'unable to create port' message.

JACK server starting in realtime mode with priority 60

When I saw the ffado message 'cannot attach audio driver', I thought it
might be a faulty firewire card, so I swapped it for another one, also
based on the TI TSB12LV26. I got the same error.
I find it quite annoying that qjackctl then goes into an 18 second retry
loop, popping up the same error box which prevents me from scrolling thru
the messages window and reading the messages until I acknowledge it, then
it gives me only 18 seconds to browse until it annoys me again. If I
wanted it to try again, I would have pushed the 'start' button again!
Grrr.
Hmmm, ffado-diag seems to tell me I have permission problems:

Should I add myself to the 'root' group, or should I change the group
ownership of that device to something else?
Anyway, here's ffado-diag run as root:

FireWire kernel drivers:
[PASS] Kernel drivers statically linked into the kernel.
[PASS] /dev/raw1394 node present and accessible.
...I tried `chgrp audio /dev/raw1394`, because I had earlier added
myself to the 'audio' group at the suggestion of jackd 0.118.
Lo and Behold! I can run ffado-diag as my own user. qjackctl will start
jack. Ardour will open my 'test' session, and play the one track there,
and after about ten minutes of playing around, not a single xrun!
