The releases 20020329 & 20020404 are dealing with the interrupts through the pci-irq-routing table and without IOAPIC. When I tested ACPI with a single-processor kernel without support for APIC's, ACPI chooses to route the interrupts with PIC. In this case the events are working without problems, with up-kernel and APIC enabled, events don't work at all, same for SMP. I don't have any idea about the cause for this strange behaviour and I'd like to enable PIC-Routing with SMP too, but have no idea how to force this.
