Nope but I will look at it.

My looks like this on kernel 2.6:

---------------------
CPU0 CPU1 CPU2 CPU3
0: 13089 0 251098584 0 IO-APIC-edge timer
1: 8 0 0 0 IO-APIC-edge i8042
5: 0 0 0 0 IO-APIC-level acpi
8: 73 0 0 0 IO-APIC-edge rtc
11: 0 0 0 0 IO-APIC-level ohci_hcd:usb1
12: 110 0 0 0 IO-APIC-edge i8042
15: 12 0 0 0 IO-APIC-edge ide1
169: 24892566 0 0 0 IO-APIC-level ioc0
177: 121556391 0 0 0 IO-APIC-level eth0
NMI: 0 0 0 0
LOC: 251145010 251145083 251145081 251145081

---------------------

using kernel 2.4 it looks like this

---------------------
CPU0 CPU1 CPU2 CPU3
0: 128904101 0 0 0 IO-APIC-edge timer
1: 2 0 0 0 IO-APIC-edge keyboard
2: 0 0 0 0 XT-PIC cascade
8: 358 0 0 0 IO-APIC-edge rtc
11: 0 0 0 0 IO-APIC-level usb-ohci
15: 2 0 0 0 IO-APIC-edge ide1
22: 68048860 0 0 0 IO-APIC-level ioc0
24: 610278021 0 0 0 IO-APIC-level eth0
NMI: 0 0 0 0
LOC: 128905644 128905629 128905632 128905638

I think you have good points about the irq beeing high.
