There is a new build of NQA out, this time it works against (and only against, sorry) NHibernate 1.2 Beta 2.
This time I also added support for Active Record. All you need to do is add the Active Record assembly to your project, add the app.config, and you are set. The only requirement is that the Active Record configuration section will be named "activerecord".
Now you should be able to execute queries against your objects directly. This release is marked as beta, since I have not yet been able to give it the testing that it needs. Let me know how it goes.
You can get the bits here.
