Ok, Just to confirm what I think you are saying: If I access I/O port 0x3f8 (COM1) it automagically goes to the LPC bus??

for
the LPC bridge.:-( It has registers to set the base address for the ACPI and
other
devices hanging off of the LPC but I cannot find the
register
that say "map this i/o or memory address space and define
the
size of the address space". I have a feeling they gave us an incomplete manual.:-(
Believe me, that's the best they can offer ;-). Those LPC devices are legacy which have "well know" fixe address.
