    One thing... the "thwarted by cache" comment probably isn't very
    useful. As far as I know the only machines which have the cache
    problem are i386 boxen, but the i386 doesn't have WBINVD. The i486
    has a pin on the CPU for A20, which takes effect inside the L1 cache,
    and so it shouldn't have any A20 cache issues.
