Updated Audiofire12 + Gentoo
 So, I wrote a few days ago how I was able to get my new echo audiofire12 working under gentoo Linux with the old firewire stack.  Well, I couldn't leave well-enough alone, so I tried my hand at updating my kernel and using the new stack.  Turned out there were a few caveats that, without some external help from a great person in the ffado IRC channel, I probably would have already reverted back to using the old stack.

First off, I'm now using the 2.6.38 kernel, even though as of now, it's still in the unstable tree.

It's imparative that you use the latest version of libraw1394, or you'll end up tearing all your hair out due to weird error messages, which google knows nothing about.  Here are the error messages I was getting when I was using the 2.0.4 version of libraw1394.  I'm now using 2.0.7, and all is well.

Error message received under 2.0.4 when starting jackd with the new stack:

...and that's that.  Now, with the new (and only) firewire stack enabled as modules in the 2.6.38 kernel, and the 2.0.7 version of libraw1394 installed, my Echo Audiofire12 works like a charm.
