Nope. It means that I can easily interchange identical VMs between  
accelerated (e.g. kqemu) and unaccelerated emulators. It works great,  
with the same command line[1], since it does not appear to change the  
hardware configuration [2].

This does not rule out KVM as future replacement, obviously, if KVM- 
specific things like virtio etc. do not interfere.
But still dropping kqemu means having an unaccelerated emulation on  
those machines not capable of running KVM due to hardware, OS or KVM- 
versioning issues.
