Oh sure, I'll take a look and will probably apply it for the next cycle,
haven't done an in-depth review. I was just surprised somebody actually
*used* the virtio thing :-)
Does that mean virt_wifi isn't used anymore by the Android emulator?
Maybe then we should remove that again, it had some obscure bugs that
