    this supersedes my last ACPI parport patch.

    PNPBIOS copied from pcmcia-cs-2.1.25 and mangled
    to fit nicely into the kernel.

    Both methods are working fine:

      linux kernel: parport: PNPBIOS found PNP0401: io=0278,0678 irq=5 dma=1
      linux kernel: parport: ACPI found PNP0401: io=0278,0778 irq=5 dma=1
      (Note: ACPI gets 0778 wrong here.)

    Tim, this would stop users from mis-configuring their built-in
    parallel ports once for all (PNPBIOS exists since 1994)!
    Will you consider this for 2.4 after some testing ?

    Regards, Gunther
