AFAIK, you can not have console on a PCI serial port at this time. I
looked at it few months back and found out that PCI initialization
happens much too late for a serial console. It would take quite a bit of
work to get serial console working on PCI cards. PA-Linux faced the same
problem but they were able to get around it by using the firmware calls
to do console I/O. If serial console were working on PCI serial cards,
you wouldn't need ACPI to use it.
