For some reason I'm not getting that message anymore. PnPBIOS is in the
kernel, parport_pc is a module. This time I rebooted with the parport_pc
module already installed, as opposed to the first time when I compiled and
inserted it without a reboot.

I'm puzzled. Just in case, it's my .config:

Anyway, the result is still the same, just without this message.
