Ok it doesn't say you need ohci1394 too and doesn't say that's the target.
If I do a new revision I'll perhaps expand the docs a bit.
So load ohci1394/raw1394 and run firescope as root. Your distribution
will hopefully take care of the device nodes. Usually you want
something like firescope -Au System.map
