Hrm.  There's a notable increase in #ifdefs, here.  It might be time
to add some CONFIG values to make this scale for future parts.  As it
is, the values being written to the iivprs are awfully magical.  It
might also be time to define some constants for those bitfields.
Whatever makes sense for making it fairly easy to see what's happening
at a high level, and to extend it next time the hardware designers
change the interrupt numbers on us.  :)
