Right.. because the BSD boxes think they are authoritative for the
reverse for those blocks.

Yes, you should be able to do this, and you're delegation looks
correct.  You'll have to do some lookups with host and dig to
find out why it's not seeing the NT delegated zone.

I would expect so, I think the CNAME PTR hack is only really needed
for delegating smaller than /24 blocks.
