It doesn't need to know about kvm, it needs to know that a particular 
hypercall protocol is available.

That's not a valid argument.  You patch as many projects as it takes to 
get it right (not that I have an opinion in this particular discussion).

At the very least you have to patch qemu for reasons described before 
(backwards compatible live migration).
