Yes, we could fix the code in the kernel, but since the family ID is
dynamically assigned and I'm trying to decouple the multicast group ID
from the family ID that would break userspace relying on
family==multicast group unless we somehow reserved the family ID number
ACPI got to make sure that ACPI gets the same multicast group ID.
Combined with the fact that ACPI might be modular and get into generic
netlink late in the game this seems non-trivial; also I think it's not
necessary since holding off on this ACPI genetlink multicast user (which
is the first besides the controller!) until we've worked out the patch
shouldn't hurt much.

Thanks.
