What may be more diifficult to understand is that gutsy is a work-in-progress, so some functionality may not exist yet. These drivers will make it into gutsy. They just haven't been given high priority yet. The majority of prism2 and prism54 are already supported, it's a few trivial IDs that aren't. We have to make sure we don't conflict drivers (which causes more problems).
