This message means that the machine 196.12.36.78 has the following in its
configuration:

zone "yvlsw.stph.net" {
  type slave;
  master { <your machine's address>; };
  ...
};

If your machine is supposed to be hosting DNS for this domain, it should be
configured as the master, not a slave.

Also, your machine doesn't seem to be connected to the network; it doesn't
respond to ping or DNS at all when I try to query it.

Since you haven't configured your domain properly, the delegation doesn't
work.

The administrator of the 36.12.198.in-addr.arpa zone can put the following
in their reverse DNS:

78 IN NS yvlsw.yvlsw.stph.net.

On your server, you would put the following in named.conf:

zone "78.36.12.198.in-addr.arpa"
  type master;
  file "db.reverse";
};

and in db.reverse you would put:

@ IN SOA yvlsw.yvlsw.stph.net. cheluvi.yahoo.com. (
                  ... ; the usual SOA parameters
                  )
  IN NS yvlsw.yvlsw.stph.net.
  IN PTR yvlsw.yvlsw.stph.net.
