All I ask is if things would break (or if you would lose a significant security property) if you were to write a `calcPrevHash` function that ignores the nonce field. I did yet another rewrite of the question to make this clearer.

If the nonce were not part of what was hashed it would a) not contribute to the blockhash, b) could be arbitrary, and c) would serve no purpose. If it's not in the hashed part of the block, why would you add it in the first place. I've already covered what it's function is in my answer, though. So, I'm really confused now.
