Why are the last messages showing eventhough ports seem to be detected and
working fine? Is there a way to disable/fix those "unknown" devices? PC is
a notebook (with APM/PnP only, ACPI is disabled).

Part of kernel:

#device         apic            # I/O APIC
device          apm

device          atkbdc          # AT keyboard controller
device          atkbd           # AT keyboard
device          psm             # PS/2 mouse

device          ppc
device          ppbus           # Parallel port bus (required)
device          lpt             # Printer
device          plip            # TCP/IP over parallel
device          ppi             # Parallel port interface device

device          sio             # 8250, 16[45]50 based serial ports
