Well, this is not exactlly an answer for your question, but take a look at version 1.2 of MyFaces:
I like MyFaces, Tomahawk, Sandbox and Trinidad...
For JBoss 5.0, we will ship Sun's version of JSF 1.2. If you build the server from jboss-head you can already play around with it. It includes resource injection and lifecycle annotations on manged beans, which is optional for JSF 1.2 but required for JEE 5.
It's not there yet, but it will also include integration with JBoss Serialization which will make JSF faster for server side state saving.
