Hmm i must say i was indeed under the impression that hybrid was == HVM + PV 
drivers.
But from what i read above it would be much more interesting by avoiding the 
qemu stuff, but still using the HVM hardware extensions.

So i think you have a point for people who don't dive too deep into what the 
actual features are.
