libdc1394 isn't part of Fedora, so that's outside the scope of this
discussion. 

As for the necessary Juju bits, they're already in Fedora 7 and Fedora
8. See this bug: https://bugzilla.redhat.com/show_bug.cgi?id=344851

That fix is included in kernel 2.6.23.9-44.fc7, 2.6.23.9-78.fc8, and
rawhide. It'll hit the *upstream* kernel in 2.6.25.

We were able to write that fix *because* the Juju stack was available in
Fedora.
