It'll raise a few eyebrows but I'll see what the chaps say.
Is there any documentation anywhere on using private setters? Do I need to
add something to the result map entries, and will I need to fiddle with the
JVM security manager?

I understand that you're using constructor injection and that they don't
have setters.
What I'm suggesting is that you add private setters and a parameterless
constructor. It won't have any impact on the immutability of your class.
It's a bit of extra code, but not uncommon. I know it's not ideal, but it
would work for the time being.
Cheers,

The private setters is a nice addition, but not really helpful in our
situation because the fields actually don't have setters at all; the object
is filled in through the constructor call.
I did pick up on some interesting conversations that you had with the the
guy who wrote O/R Broker, which seems to have a nice pattern for dealing
with constructors and complex loading statements (like loading up a field
based on the contents of another field). Hopefully we'll see something
similar in IBatis in the future.
Thanks for your help ... :-)

As a temporary alternative we do support private setters as of 2.2.0 .
Constructor injection is supported in the .NET version. The two codebases
are somewhat similar, so we could always check on their approach to it.

I remember some folks asking about this, but no commitment to do it. It
would require quite a change to the way iBATIS processes result sets.
Translation: don't expect this anytime soon.
BTW, the Sun patterns web site has some information about an immutable
transfer object pattern here:
http://java.sun.com/blueprints/patterns/TransferObject.html
The basic idea is that you create an interface for the immutable part, and
a mutable static inner class for initializing. This does work with iBATIS.
But one warning - we used this pattern on my team for a while and everyone
(me included) HATED it. So we eventually went to simple JavaBeans with
getters AND setters.

Mmm ... no that's not quite it.
I have a set of VO classes that are immutable. This means that all the data
is added at construction.

I am not finding docs for it at the moment, either. I think that the
ResultObjectFactoryTest unit test does what you want. Take a look, and
see - if it is, please feel free to add a page to the WIKI
(http://opensource.atlassian.com/confluence/oss/display/IBATIS/Home )
on how to use it.
