What happens if you ommit hw:0?
As in:

jackd -R -dfirewire -r48000 -p1024 -n3

I don't think there is a -d option for the firewire driver in jackd. 
Try setting "Interface" to "(default)" when you have selected "firewire"
for the "Driver". It seems to work here in fc11 (with no firewire card
attached but at least the command line does not include a -d hw:0).
