Just an updated kvm-79 userspace *should* work; for instance, in oVirt, we are running a kvm-79 userspace equivalent on a 2.6.27 kernel, which is slightly older. In general, a new kvm userspace should work on an older kernel, but it is not a heavily tested configuration, so your results might vary.
