reverse DNS RFC 2317 5.2

My co-lo ISP is having troubles allocating the reverse DNS lookup to my nameservers.

I do believe that their dns servers are not properly delegating the in-addr.arpa domain to my nameservers.

After setting up my DNS servers for reverse lookup of my IP addresses using named.conf:

zone "x.x.x.in-addr.arpa" IN {
type master;
file "named.x.x.x";
allow-update { none; };
};

and in named.x.x.x :

---snippet---
x.x.x.x.in-addr-arpa. IN PTR ns1.***********.
---snippet---

This setup returned the PTR record upon a reverseDNS lookup specifically from my server with no problems, however it could not be resolved from any other DNS server globally.

Now they want me to comment out the in-addr.arpa name.conf and add PTR lines to my main domainnames DNS file like this ( they pointed me at RFC 2317 5.2 http://www.faqs.org/rfcs/rfc2317.html ):

ns1 IN A x.x.x.x
host-x-x-x-x IN PTR ns1.xxx***********

Reverse DNS is not working with these settings either... has anyone ever setup a reverse DNS without controlling the in-addr-arpa domain?
