Richfaces portlet bridge deployed in the Jboss maven repository, http://repository.jboss.com/maven2/org/richfaces/extensions/portlet/3.1.2.GA/ .
You can get sample portlet project from SVN https://svn.jboss.org/repos/richfaces/tags/3.1.2.GA/samples/ajaxPortlet
In the next Richfaces release, it will be converted into JSR-301 compatible implementation.
You can get build it from code in the SVN trunk (https://svn.jboss.org/repos/richfaces/trunk) or got from nightly builds, from Jboss Maven snapshots repository - http://snapshots.jboss.org/maven2
Thanks!!! That solved one of my problems.
