Yes, you can maintain a list of custom messages in an appropriately scoped component. Observe the event as you are and add the session expired message to your message component. Then prior to rendering the login page, invoke your messages component to add the messages to FacesMessages (which you can do by specifying an action in pages.xml). FacesMessages will be available in the context at that time. This serves as a workaround which I have used on several occasions for messages that are initiated prior to the RESTORE_VIEW. Also, if anyone else has a better way to initiate messages prior to RESTORE_VIEW I would certainly like to hear it :) Hope that helps.
