Irq 2 is called the "cascade interrupt". Pc-xt's, which have only one interrupt controller, have 8 irq's, but in at's a second controller is cascaded from the primary interrupt controller's irq 2 to yield a total of 15 usable interrupts (because you cannot use irq 2 for a real interrupt anymore.) Read a pc-hardware faq if you want to know more about this. So unless you are running linux on a 8086, you can forget irq 2, I think.
