Qemu does not emulate the 440 core, but that's what our KVM code
supports. Bamboo is a 440EP reference board, so the Bamboo setup will be
useless to qemu until they get 440 support.

That said, there are only 2 places that we make KVM-specific calls in
this code, and those can easily be protected with "kvm_allowed" checks
in the future.
