Oops. I just ran a bunch of tests on my Mac OS 10.6 system---does that mean that I compared two sse2 backends? The ocaml-sse2 branch definitely produced different code than the trunk, but that could easily be due to any small difference in the two compilers, and not due to a change of architecture.
