I don't think qemu can get notified on either cpuid or #GP faults, can it?

A big chunk of the functionality here is to allow a userspace process to 
transparently make the "hypercalls" without the OS needing to explicitly 
give it access to the IO space, by trapping the resulting #GP faults and 
checking to see if they are IO instructions .  If that's functionality 
we think is important, then it will have to be done in Xen, I think.
