I am doing separate zone files. Each IP delegated to me is a separate

      Technically, nothing -- at least, with the absolute latest 
authoritative nameservers and the absolute latest recursive/caching 
nameservers, and it doesn't seem to give much problems to modern 
resolver libraries.

['it will break with lots of software']

I am very willing to believe everything that you are saying, but *what
part* of my configuration breaks those nameservers?

o The reverse zone contains one or more A records
    The reverse domain "192.122.109.193.in-addr.arpa." contains one
    or more A records.  A records should only be placed in
    forward-mapping domains.

What A-records is it talking about? I am not seeing any.

      They are the ones associated with your NS records.  At a 
procedural level, PTR records are mutually exclusive with SOA & NS 
records.

But there are no A records in that zone. Again, what A-records?

I have, by the way, enabled AXFR to the world for my reverse zones
(all 16), so feel free to have a look.

Also, I am aware that the hostmaster-address in the SOA for these
zones is bogus - I will fix that shortly.

Greetz, Peter
