IRQ is the term used in the 8259 Programable Interrupt Controller, for
the input pins used to accept Interrupt ReQuests.  INT is the term used in
the Intel CPU mnemonics.  Since the IRQ is fundamentally a hardware entity,
the only way to 'intercept' it is to intercede at the hardware level, by
rearranging jumpers, cutting traces, and other unnatural acts.  However,
there is the possibility of intercepting the software interrupt service
routine invoked by a hardware interrupt, since the CPU INTerrupts are mapped
one-to-one to IRQ's.
