 I suspected so. Is this the same thing is true on a 2.4 kernel
(pcmcia-cs is not
handling that, bot hotplug ) ?

 The kernel is 2.6.12 (Ubuntu latest stable, fuzzy or something...).
I'll upload a dmesg
from the system later, I don't have access right now to it. I noticed
some messages
for the PCI device in the form: 'ACPI : disabled interrupt ... for
device xyz' so I booted
with various kernel parameter configurations (no ACPI, pci=noacpi and
pci=routepirq, not sure if the last combination is correctly typed now
in the email) and noticed that IRQ for the device changed. I believe
that the serial driver (8250_pci) is built into the kernel
(I'll upload the kernel's .config also).

 I'll give more details later,
