I am using a modular serial driver on /dev/ttyS0 and /dev/ttyS1 (actually /dev/tts/0 and /dev/tts/1 under devfs). See the listing of my /proc/interrupts below. I am not using /dev/ttyS0 at the moment, so IRQ4 isn't listed as used. I assume that's normal. But I do have /dev/ttyS1 open; it uses IRQ3. But note that the name of the serial driver is not printed in the list.
