Well, that was really close. qemu-kvm-0.12 has the
following code in that place:

      vdev->features = features;

the patch mentioned has this:

+    if (vdev->set_features)
+        vdev->set_features(vdev, features);

so basically kvm had the same code here,
just not wrapped into a function ;)

And sure thing you're right, it does not help any. :)

Thanks!
