hmm.. well I'm not currently interested in implementing all of the
DS stuff. I just wanted to standardize the way we tell hw level drivers
about the priorities. I suppose using the standard PHBs for this would
make it easier to add DS in the future if anyone wanted to. Do you know
where I could find a list of standard PHBs?
