The 8250 core preallocates a number of ports for use, see
serial8250_isa_init_ports() and serial8250_register_8250_port(). As the
serial port driver probes, the preallocated ports get re-assigned to
the port driver.
Maybe we could keep the static serial8250_ports[] and add those ports
to a list where also the dynamically allocated ports would go..

Tony
