Yes, running -cpu n270,+movbe with Richard's patchset merged works.
Thanks.

This is problematic since the n270 qemu model won't boot a real kernel compiled
for that box.

It wouldn't be a bug fix without extracting the patch out of
my x86-next tree that actually implements movbe. I

The Atom core (cpu name "n270" in QEMU speak) supports MOVBE. This is
needed when booting 3.8 and later linux kernels built with the MATOM
