Yes, add raw1394 to /etc/modules.

Enable raw1394 should probably have a more descriptive title. It does
not load the kernel modules for you but rather, fixes udev permissions.
Speaking of which, having -controls add raw1394 to /etc/modules is not a
bad idea...

When you modprobe raw1394, do you still get the error message with jack?
