That's right, but right now, we simply try to register all of memory from 
KERNELBASE to high_memory, which works right until we have memory holes in 
the middle; then the hypervisor will reject our page registrations. Same 
goes for huge (16GB) pages, by the way. We're working on a solution to 
this.

Cheers,
