Regardless of the setting - it seems that the disklabel continues to be cached - and thus no updating of the /dev's (e.g. matching the actual slices/partitions) happens. I guess that we need a firewire.force_update_on_reconnect which completley wacks any disklabel/da -or- perhaps abandons trying to use the lowest number possible; but keeps on counting it as a higher one.
