"serial" does not show up in /proc/interrupts

I am looking for the cause of an oops (more info
to come in another message) and I noticed the following
anomaly. 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. Why not?
