Yeah, but if we put a feature in qemu, we need to be able to support it 
for anyone who wants to use it.

Adding something for a very particular test suite that won't work in 
normal circumstances is just asking for trouble IMHO.

I still don't really understand all the pieces that are involved here.  
Why do we need a guest physical address?  Are we testing reflecting MCEs 
from the host into a guest?  Since that functionality isn't in qemu 
aren't we putting the cart before the horse here?
