    This is my old SMP test machine using Intel R440LX motherboard (dual
    Pentium II 266 MHz, no ACPI - AKA "RedWood"):

    PCI quirk: region 0c00-0c3f claimed by PIIX4 ACPI
    PCI quirk: region 2180-219f claimed by PIIX4 SMB
    PIIX4 devres C PIO at 0ca8-0caf

    According to the HW tech ref they are "Server management mailbox registers":
    0CA9h DISMIC Data Register
    0CAAh DISMIC Control/Status Register
    0CABh DISMIC Flags Register

    and are some early (incompatible) version of IPMI (SMIC) bus/controller.
