No, I agree with that.  I just disagree with choosing to put the *pic 
code (or other code) into the kernel on *that* basis.  The selection 
should be on design/performance issues alone, *not* the state of 
existing code.

No.  But the difference in cruftiness between kvm and qemu code should 
not enter into the discussion of where to do things.

I agree with this, maybe for different reasons.
