There are _two_ sets of kernel modules that implement firewire. Fedora
includes in their kernels the new firewire "stack" of modules and
regretfully FFADO is not working yet with those. So no amount of
tinkering will make FFADO work with the Fedora kernels. 

I'll try to think of something later (busy morning).
