I ended up never installing 9.04 (Jaunty). This time around, I even made my way to a release party (at Gnutiken) to install the latest Ubuntu release. I have to say, it was a painless and quick process and everything seems faster (it might also be because I installed the 64 bit version...).
This time, I installed the regular Ubuntu, instead of Ubuntu Studio. The steps to get things going from here:
1. I installed linux-image-rt (the realtime kernel)
2. I installed some audio software (apt-get install ardour hydrogen gave me most of the necessary stuff like jack and qjackctl).
2. I added my user to the 'audio' group and logged out / logged in.
3. To get access to the firewire device, I did modprobe raw1394 and chmod a+rw /dev/raw1394 (I learned this from my own blog)
4. I set up qjackctl to use the FFADO plugin with a buffer size of 512 and it worked!
I haven't been able to test it much yet, but playback from Ardour seems to work fine enough. Hooray for 9.10!

First steps - I've got sound!
I have now installed Ubuntu 8.04 (Hardy) on my laptop. Sadly, Hardy's ATI drivers for Xorg don't seem to support my ATI Mobility Radeon HD 3400, so I have to run proprietary drivers for now.
One possibly good piece of advice for anyone looking into Linux audio (or Linux in general) is "don't buy a laptop model that's too new!" or you will need a load of patience to hack around with it - sure, Ubuntu 8.10 recognizes most of my hardware, but in this case, I need to run 8.04 to get real time capabilities.
After some googling and hacking (among other things, I followed this thread about making Jack work in real time mode) I can now get sound through the Edirol FA-66. FINALLY!
Everything's not fine, though. Jack has crashed a couple of times during the last 20 minutes, Qjackctl seems to be inclined to freeze, and there is some annoying crackling and popping going on during playback in Ardour - although neither Qjackctl nor Ardour registers xruns (Ardour does, however, detect "spikes" in master output).
On one hand, I'm glad that I've gotten this far. There's definitely a sense of accomplishment, and I'm hopeful about this whole project. On the other hand, there are obviously some issues to be dealt with before I've got a stable, working setup.
