    I don't think anyone uses ioports > 32bit. Certainly i386 takes an int
    port as parameter to {in,out}[bwl] (and it really only uses 16-bits).
    parisc uses 24 bits. I don't know what the various ppcs do, but pci
    bars can only be 32-bit for ioports. So my opinion is that ioports
    should be uint, not ulong.
