Well, I don't understand the AT/XT architectures.
However, my limited understanding is that currently serial and parallel
ports are always reached by well-known IRQs and well-known port locations,
via the ISA bus. I don't know of a supported way to put them on the PCI
bus instead.
New BIOSes support USB, I believe.
