I might be jumping into the middle of this, so sorry if this isn't the
answer you are looking for...but,

1.  To stop your server from caching negative response from other
servers see Mark's suggestion on max-ncache-ttl (it is in the ARM).

2.  To set the negative caching for zones you host, see RFC 2308
(Section 4) here:
ftp://ftp.rfc-editor.org/in-notes/rfc2308.txt  


That's all I got to say about that...
