We don't cast, we use a method.

The XSCOM controller has a different address decoding scheme, so
we'll have two variants and a base class there. The number and
location of functional units changes, so we'll probably need to make
them properties or something, the core XSCOM addressing is completely
different, we use PHB4 rather than PHB3, etc...
(Note that for PHB we should probably rename PHB3 to PnvPhb with a
subclass as well as there is a lot in common between the two, though
the PBCQ bit is quite different).
Cheers,
Ben.
