Nope. The old logic was broken. The new logic works correctly, but does
so only on new kernels. If you run it on old kernels, it will gracefully
ignore the id attribute.

So, no, it doesn't require the new kernels. It will just start working
correctly on new kernels. And on old kernels you will not get the id
appended to the name, that's all.
