...and as implemented, this will only kick in if your OpenSSL version
does not support SHA-2 at all, so *any* speed is good speed. So
obviously I think this is very good stuff.

Simon, or Tavis, don't you feel a sudden urge to implement damn good
SHA-2 intrinsics into JtR? Actually, we can make this a contest: Which
one of you will be first? And which one of you will be best? Maybe we
can manage to offer some kind of prices for each of those sub-tasks :-)
