Actually, the mouse _isn't_ a polled device (i.e. the mouse driver only
gets called when the mouse moves, or a button is pressed, etc.). That's the
whole point of interrupts, you don't have to check a device however many
gazillion times a second. So the interrupts on the 86 would be more like a
timer interrupt. Although that's kind of beside the point...
