Ok, sounds like a plan.

The problem is that I get "jackd: unknown driver 'firewire'" when
starting jack, (much) more info follows:

I added the following to /etc/apt/sources.list:
deb http://www.ffado.org/apt gutsy contrib

and installed:
apt-get install libffado2 ffado-tools ffado-dbus-server ffado-mixer-qt4

running the ffado-dbus-server seems to work just fine (it should be run
as regular user and left running, right?):
