I guess I could see doing the first patch (just support multiple
vectors in the kernel without changing any drivers).  That way it
would be easy to experiment with patched drivers that enable multiple
vectors.

I think there's still some figuring out to do about how many EQs to
enable, etc, and I think it would be better to prevent drivers from
escaping into the wild before we have a better handle on the issues.
