Well, field access is implemented. See the tests here for an example:
http://code.google.com/p/fluent-nhibernate/source/browse/trunk/src/FluentNHibernate.Testing/DomainModel/Mapping/AccessStrategyPropertyMapTester.cs
You just can't map fields directly. You have to map the properties and
then specify the Access strategy.
