this option exist for kernel 2.5.x I believe, but for kernel 2.4.x don't.

look for this part of the kernel code :

 #ifdef CONFIG_ACPI_PCI
       if (!acpi_pci_irq_init())
                pci_using_acpi_prt = 1;
 #endif

After testing the kernel with acpi_pci_irq_init()> 0, I realize that pci
irq routing works different, because the function acpi_pci_irq_init
returns 0 and pci_using_acpi_prt is passed with zero (= 0) . 
so I ask for your opinion, if with one boot parameter (for example
acpi=nopci), we don't call acpi_pci_irq_init and assign pci_using_acpi=0
, kernel will work like having boot option pci=noacpi?
conclusion it is possible acpi work without calling acpi_pci_irq_init
etc.. ?

This is for trying resolve the problem of the people whose computer
hangs on boot with pci-irq problems.

PS I send right now the patch for this propose if you think that can be possible and correct.
I just test in my compaq pressario 706EA Laptop. 
new boot param :
acpi=nopci.
