I'm running on real hardware.  I didn't think the simulators supported the SPE (Signal Processing Extension) instructions, but I might be wrong, I just googled it and found this for QEMU for 2007:

Log message:
        PowerPC 2.03 SPE extension - first pass.

It won't help with my code, but maybe I can try running the tests with QEMU.  If anyone has QEMU and is familiar with it you can check and see how complete the support seems to be.

Tomorrow I'll build a toolchain with the RSB.
