There is more correct way to do that in Karmic.

1. Before.

asmok at ubuntu-studio:~$ ls -al /dev/raw1394
crw-rw---- 1 root root 171, 0 2009-11-28 08:53 /dev/raw1394
asmok at ubuntu-studio:~$

2. Add new file with this line in correct directory.

asmok at ubuntu-studio:~$ cat /etc/udev/rules.d/50-raw-firewire.rules
KERNEL=="raw1394", NAME="raw1394", GROUP="audio"

3. After REBOOT.

asmok at ubuntu-studio:~$ ls -al /dev/raw1394
crw-rw---- 1 root audio 171, 0 2009-11-28 09:30 /dev/raw1394
asmok at ubuntu-studio:~$

asmok at ubuntu-studio:~$ /usr/bin/jackd -R -m -dfirewire -r48000 -p64 -n3
