Be careful about source code layout, please.  Some people think
that it's "the NetBSD way" to mash source code into small
segments and play acrobatics to compose them with heroic includes.
The way does not contribute portablity, "how easy the code reused
in future," in other words.  SoC is, by definition, the product of arbitrary
combination of pieces similar but different in all the details.  It's the
nature of SoC and code sharing does not always help how well it's is
designed for retargeting.  I think the worst is hpc* ports which I hate
to see.
