    What are the port addresses? For ISA serial interfaces the GENERIC
    kernel has the IRQ-port combination hard coded for each serial interface,
    so even though both the IRQ and port might be valid, if they're not
    paired correctly it won't find them.

    com0 at isa? port 0x3f8 irq 4 # Standard PC serial ports
    com1 at isa? port 0x2f8 irq 3
    com2 at isa? port 0x3e8 irq 5

    Also, does the Thinkpad try to do `Plug n Play'?

    Cheers,
