Anyway, it causes acpi_disable_pci() to be executed, which according to Documentation/kernel-parameters.txt means "Do not use ACPI for IRQ routing or for PCI scanning" (it works like this on x86_64 too, although the doc says it's x86_32-specific). And yes, it matches "noacpiwhatever" in the command line with "noacpi".
