I don't have the same issue with the recent kernel, so it's not the
kernel.
The message is puzzling, since you do have the stack. It is there, just
not active in your case.
I would suspect a hardware problem. And that could be related to the
kernel version, that the most recent firewire drivers don't work on your
hardware. 

You could just download and install an older kernel version and see if
that makes a difference.
You can find all the packages for linux-lowlatency here
https://launchpad.net/ubuntu/+source/linux-lowlatency

For me, the stack is present and loaded.

Check with the ffado folks on their mail list if you can find out
something more.
