For what it is worth I have run into the lack of a knob to control the
negative cache TTL as well. I am currently looking at replacing some
BIND based resolvers for a fairly large site and they are running with
"max-ncache-ttl" to force a lower TTL of NXDOMAIN results.

I realize this might qualify as feature creep and I have been thinking
that not having the functionality could be considered a good way to
force people to fix the SOA minimum field instead. I guess this is not
always feasible though.
