So long as the PTR record for your IP address can be matched against an A
record, it should all work fine. It doesn't matter that the records come
from different servers.
In other words, this will work:
1.0.168.192.in-addr.arpa. PTR www.domain.name.
www.domain.name. A 192.168.0.1
But this won't:
1.0.168.192.in-addr.arpa. PTR domain.name.
www.domain.name. A 192.168.0.1
(assuming that there is no A record for "domain.name.")
This also won't work:
1.0.168.192.in-addr.arpa. PTR www.domain.name.
www.domain.name. A 192.168.0.10

I would demand a classless subnet delegation, since it's really pretty easy
if you understand RFC 2317. But then, I am not their customer. However, if
they give it to you, it means they never have to worry about ongoing
maintenance with regard to your PTR records (when you change host names),
and it just takes a few minutes to set up.
If it makes them more willing to give you this service, you can tell them
that you won't need them to explain how it works. If you need help setting
it up, you can always ask me. =>
