    Because it's much cheaper to buy an off-the-shelf southbridge, even if
    you're not going to use the ISA bus for any devices if you're making an
    ISA-less mainboard, than trying to find or even design one without an
    ISA bridge in it.

    I recall people using the vt82c686a's with StrongARM CPUs even ...
