There are a couple of places where you use "1" (when no other size is
available). e.g. in get_page_addr_code().

Wonder if that's the right thing to do - are there any architectures
that e.g. always fetch at least 2 bytes in these conditions?

Apart from that, looks sane to me (for other architectures :) )
