udev makes /dev/raw1394, but no module

I've been setting up dvgrab to get some dv off my camcorder. I kept getting an error message raw1394: no such device. But /dev/raw1394 did exist, as did dv1394. The problem was that neither the raw1394 nor dv1394 modules were loaded. udev should be loading the modules, correct? But why is it creating the /dev entries if it's not loading the modules? Is this a feature, or a bug? Does udev only create the dev entries, and the user is supposed to load the modules? sean
