The PNP0C01 ports are not used by the kernel ! No modifications necessary.
Of course you can teach each driver about their PNP devices, e.g. my patch for parport_pc.c makes perfect io/irq/dma detection and saves users from the error-prone procedure to supply module parameters. Even serial now autodetects IRQ 10 when I give this in my BIOS setup !

So we have another way besides several INTs to detect the avail mem :-)

Gerd's patch rules out your objections and should be included unconditionally with pnpbios.o.
Probably PNP0C02 wants to be reserved, too. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
