Yeah, I've got a bug open in Debian (#740034), I certainly don't mind
if you add your patch there since it is still open. Actually, I need
to increase the severity now since arm64 is part of the archive.

Well, if it is negatively impacting shipping hardware (i.e. lshw is
unable to report certain things because of the lack of smbios
support), I'd say "High" since I consider that a hardware enablement
issue. If it's just a correctness thing at this point, my opinion
would be wishlist. That's just my opinion though, feel free to use
your own judgment.
