Does acpi=off make a difference and change how /proc/interrupts looks?
If yes, can you try the latest ACPI code that 2.6.5 is missing?

Correct on all counts. acpi=off changed how /proc/interrupts looked.
Plain rc3-bk2:
cat /proc/interrupts
CPU0
0: 24465969 IO-APIC-edge timer
1: 3894 IO-APIC-edge i8042
2: 0 XT-PIC cascade
8: 1 IO-APIC-edge rtc
9: 0 IO-APIC-level acpi
11: 0 IO-APIC-edge ohci1394, radeon@PCI:1:0:0
12: 208554 IO-APIC-edge i8042
14: 484633 IO-APIC-edge ide0
15: 24 IO-APIC-edge ide1
16: 100000 IO-APIC-level CMI8738-MC6
18: 96443 IO-APIC-level eth1
21: 0 IO-APIC-level ehci_hcd, uhci_hcd, uhci_hcd, uhci_hcd
With acpi=off:
cat /proc/interrupts
CPU0
0: 411879 IO-APIC-edge timer
1: 1037 IO-APIC-edge i8042
2: 0 XT-PIC cascade
8: 1 IO-APIC-edge rtc
12: 15358 IO-APIC-edge i8042
14: 13668 IO-APIC-edge ide0
15: 24 IO-APIC-edge ide1
16: 21258 IO-APIC-level ohci1394, CMI8738-MC6, radeon@PCI:1:0:0
18: 404 IO-APIC-level eth1
21: 0 IO-APIC-level ehci_hcd, uhci_hcd, uhci_hcd, uhci_hcd
And the patch worked.
With the patch:
cat /proc/interrupts
CPU0
0: 138277 IO-APIC-edge timer
1: 942 IO-APIC-edge i8042
2: 0 XT-PIC cascade
8: 1 IO-APIC-edge rtc
9: 0 IO-APIC-level acpi
12: 918 IO-APIC-edge i8042
14: 11189 IO-APIC-edge ide0
15: 24 IO-APIC-edge ide1
16: 7731 IO-APIC-level ohci1394, CMI8738-MC6, radeon@PCI:1:0:0
18: 177 IO-APIC-level eth1
21: 0 IO-APIC-level ehci_hcd, uhci_hcd, uhci_hcd, uhci_hcd
Thanks for all your help. When should we see the patch in the kernel?

That's it! I'm taking the rest of the week off;-)

Marcelo pulled it into 2.4.26 yesterday.
Linus pulled it into 2.6.5 this morning.
Thanks for the quick feedback!
