It's easy:

http://ieee1394.wiki.kernel.org/index.php/Juju_Migration#Module_auto-loading


Compile both modules and blacklist the new Juju modules. That's the
current upstream recommendation.

Even if the default will change around 2.6.30 (or later, I don't know
the exact schedule), the FFADO users could still enable the old ieee1394
modules.

We already have libraw1394-v2 in sid, but as outlined, FFADO currently
only works with the old stack. This might also change in the future,
especially if the Google Summer of Code project succeeds. (in-kernel
alsa driver module for firewire audio)


IOW: ship both stacks, decide for one and blacklist the other. FFADO
users will then select the appropriate one. And of course, I'll continue
looking into the FFADO-on-Juju issue.
