	Yes, you can forward unresolved entries (those not in your
	domain or in your secondary zones) by using the forwarding
	construct in named.boot.
	; forward name-service request when we can't (won't) handle them

	I do not really understand.  I would answer your question with no.
	The in-addr.arpa domain is rather unusual and should be treated 
	differently than most others.  The declaration in named.boot 
	specifies service for a particular domain.  I think that your 
	declaration would break unless it were of the following form:

	named.boot
	----------
	primary 207.128.in-addr.arpa.		herb.file_name
	
	herb.file_name
	----------
	$ORIGIN 254.207.128.in-addr.arpa.
	44	IN	PTR	parsley.herb.blah.blah.
	$ORIGIN 253.207.128.in-addr.arpa.
	1	IN	PTR	oregano.herb.blah.blah.
