Jan and Paolo,

Ok, I thought a little bit about this and I am wondering what 
kind of tests we could have here. All the changes are pure 
checks and no data is returned back to the guest. The
vmxon code in kvm-unit-tests already does the right thing i.e
sets the revision identifier, allocs a page for the region etc
