Is there a way of querying a slave server/zone and obtaining a list of valid

No. The zone data does not record where it came from, unless you put
that information in on purpose.
All of the listed NS records should serve the zone and one or more
of them may allow AXFR from a host that it recognises as a valid
secondary, but you don't know which (if any) of these was the
primary. It could easily be none of them as a hidden primary server
is a very common setup.

I'm sure the answer is still, "no", but I don't think I expressed my
question properly. What I'm after is a list of IP's a given pdns slave
will accept as acceptable NOTIFY masters for a given zone. So, given a
combination of NS records, configured supermasters, allow-notify-from,
etc., what are the possible valid IP's?
So when I get a, "pdns_server[xxx]: Received NOTIFY for example.domain
from 1.2.3.4:13376 which is not a master (Refused)" I could compare that
to the "valid" list. Since I have "1.2.3.4" listed with an NS, and in
"allow-notify-from", and configured as a supermaster - and it's still
not going through - I'm looking for possible answers.
Daniel
