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.

Thanks,
