I don't think we ever had a JBoss 4.4.
You will probably want to upgrade to the latest version of JBoss EAP. The community version, WildFly 8, makes it very easy to use any JSF version from 1.2 up. See Design of WildFly Multi-JSF feature.
There is always a built-in version of JSF based on Mojarra. Your JSF 1.1 application should run just fine, but there are a few known issues with upgrades from such an old JSF spec. You'll need to search to find them.
