It looks like you need ACPI and I/O APIC support active. This would add
interrupts 16-23 probably and spread out the load. My complete list
(nForce2, Geforce4 graphics, Atheros wifi, 3xDVB card, 1xextra sound card):
hamish@tv:~$ cat /proc/interrupts
CPU0
0: 203837872 IO-APIC-edge timer
1: 11 IO-APIC-edge i8042

22: 103718 IO-APIC-level NVidia nForce2
There's still some sharing (SATA controller, sound card and wireless,
plus one DVB card and Geforce4) but that hasn't been an issue for me.
You may have to upgrade to kernel 2.6. Not a bad idea anyway..
