If you are using an Athlon then you might have a VIA chipset and apparently non-intel chipsets can have these sorts of interrupt problems (Via especially). Try changing to an intel chipset motherboard.
On an Intel P4 board I still get the 3s spikes. The spikes are "wider" on the plot, i.e., taking more than a 1s interval. With irq balancing the interrupts alternate between processes.
