I have no COM port on notebook (without port replicator which I do not have)

partially defeats the purpose of disabling COM port - the intention was to
free resources by *not* loading unneeded modules ...
This may have something to do with (ACPI) PnP which apparently believes COM is alive.
Notebook is Toshiba Portege 4000.
Probably a BIOS bug. It still lists the port in PnP data even though the
hardware is disabled, so the kernel still tries to load the serial
driver for it, which finds there's no port there.
