Again, no abstactions please.  Get this working and merged properly
first, before worrying about any sort of additional hardware models or
abstractions.  It just makes this so much harder to review and to
determine what you really are, or are not, using here.

So far, it seems you aren't using any of these new abstractions, which
is odd.  Or I just can't find them.  Either way that's a huge sign this
code is wrong and needs to be cleaned up.

thanks,
