Fixed a bug that would cause bogus Message-IDs on BONE systems. It seems that our utsname structure is 8 times larger than BONE's, so all the offsets are screwed up when you try to link our headers against BONE libraries. If we're really aiming for BONE compatibility in our network stack, perhaps this should be changed.
