Are there portions of the XNA framework that get benefit from the VMX instructions available on the Xenon processor The quaternion discussion got me researching it, but I can't find any discussions at that low level.

The current answer is that the VM will not generate VMX instructions. It may be that some of the system libraries do, but also, many of the system libraries are themselves written in CLR and thus not that efficient. (This is sadness for things like matrix, quaternion and vector)

So, right now, I think the general answer is "VMX is not used a lot when using XNA 1.0 on Xbox".

Thanks. Maybe in version 2.0.
