I looked at the JNDI View in jmx-console and I'm finding that I am able to bind to the java:/ namespace from the jboss-service.xml (using JNDIBindingServiceMgr mbean). But I guess I'm approaching this the wrong way since I am binding the custom data source object under the right jndi name thinking this was all that is required but in fact it also needs to be recognized as a DataSourceBinding service in order for the dependency from my EJB to the data source (in the persistence-unit definition) to be resolved.
