For the registerised port, you really need a native code generator

the NCG would take a couple of weeks or so for someone unfamiliar with
the code. Hopefully we'll improve that when we refactor the NCG as
part of the backend overhaul.
Is there any documentation on the NCG? I ported 6.6 to HPUX 11 some
time ago
and looked at the NCG but didn't do it for PA-RISC because it was going
to take too
much time to understand. I was leaning towards the approach of trying
to translate
the code generator for another processor into PA-RISC.
There's some old documentation, some of it is still relevant but probably
much of it is out of date now:
http://darcs.haskell.org/ghc/docs/comm/the-beast/ncg.html
the best doc is the code, I'm afraid (but it has lot of illuminating
comments and you can get a long way with cut-and-paste).
Cheers,
Simon
