    How interesting. I was under the impression that dev->sysdata was always
    a copy of the bus's. If that's not guaranteed, then we're just going
    to have to dereference the additional pointer and use the bus' sysdata.

    "Next the statesmen will invent cheap lies, putting the blame upon
    the nation that is attacked, and every man will be glad of those
    conscience-soothing falsities, and will diligently study them, and refuse
    to examine any refutations of them; and thus he will by and by convince
    himself that the war is just, and will thank God for the better sleep
    he enjoys after this process of grotesque self-deception." -- Mark Twain
