What about an FPU?  It probably wouldn't eat much power, and would help 
a *lot* for audio applications, since stuff wouldn't need to be 
rewritten in fixed point arithmetic.

On a related note (and perhaps on the wrong end of an NDA), any idea 
what the specs are on the glamo's built in openrisc processors?

Can they do floating point?  Randomly access memory?  How many of them 
are there?

If they're beefy enough, with the right drivers (like CUDA), I think 
we'd have the bus bandwidth to offload audio processing (ogg decoding) 
to them, assuming the bus is symmetric:

48khz * 16bit/sample * 2channels = 187.5 kilobytes / sec = 1.4 mbit/sec
