    Yes, in theory. Lava get this right I think, but I don't think anyone
    else does. Take a look at the existing table entries, for instance,
    and see that the base address registers are all over the place. You
    can't even reliably tell how many parallel ports there are even
    supposed to be without other knowledge.
