No they don't need to be reported as the same interrupt. Just look at
APIC vs non-APIC. IRQ11 looks like non-APIC, IRQ16 is most likely APIC
driven.
If you have agp in your kernel, remove that line and preload the
nvidia.ko from the bootloader. That way my system works with a 5900XT.
(nforce2, no apic, acpi enabled)
