Version numbers are the last resort. We'll try all other avenues for
detecting a feature, before turning to a version number, precisely
because of the variance you mention here. When we do toggle something
based on a version though, we'll be conservative basing decision off
upstream QEMU 0.13 functionality, ignoring what extra bits a distro 
might have backported (or even disabled).
