We are 100% positive that the data is compliant. We can even add the
records in question to the slave via a manual slapadd with no problems.

As Dave Lewney pointed out (the answer to the original question), a 2.1
slave won't work with a 2.0 master, so this is not possible. I am guessing
that the same is with a 2.2 slave with a 2.0 master, although I would sure
like to hear otherwise.

Yep, we know. 2.2 has lots of useful replication features that we'd like
It looks like we'll have a very challenging upgrade to do, if the master and
every single slave need to be upgraded at the same time.
