Yeah, good catch.

I'm working on the i830 overlay for Xv at this point. It's completely
broken; it doesn't work at all on pipe B and when used on pipe A, it
locks up on the second attempt to use it. It looks like the lockup is
caused by the overlay failing to shut down for some reason, and I think
the failure on pipe B is caused by memory priority misconfiguration. At
least I hope so.
