No, ACPI is not required for interrupt sharing... So it might work ;-)

Have you tried my patch? I'm running a kernel with this patch, ACPI enabled
and "pci=noacpi". 16 IRQ's won't be enough for me, too, as you can see here:

CPU0
0: 348795 IO-APIC-edge timer
1: 627 IO-APIC-edge i8042
2: 0 XT-PIC cascade
4: 5 IO-APIC-edge serial
8: 2 IO-APIC-edge rtc
9: 0 IO-APIC-edge acpi
14: 12240 IO-APIC-edge ide0
15: 11 IO-APIC-edge ide1
16: 31827 IO-APIC-level nvidia
17: 1461 IO-APIC-level eth0
18: 4 IO-APIC-level bttv0
19: 13213 IO-APIC-level EMU10K1
21: 11567 IO-APIC-level uhci-hcd, uhci-hcd, uhci-hcd, ehci_hcd

And everything works just fine... (despite my broken BIOS ;-)
