    I'll fix it.

    pbe collides with abuse by at least two vendors (AMD and
    Cyrix/Centaur/VIA) of this bit for 3DNow. I don't know if that applies
    only to the chips that don't support extended CPUID levels, but I'm
    fairly sure that we don't handle that correctly in the vendor-specific

    I guess for now we can just unconditionally disable that bit in those
    vendor routines, with a note saying that if there are such chips
    supporting PBE then more sophisticated logic needs to be implemented.
