Do you have a PS/2 mouse enabled/configured in 2.4?
I do, and it shows this on 2.4.20:

  0:   78505022          XT-PIC  timer
  1:     305438          XT-PIC  keyboard
  2:          0          XT-PIC  cascade
  3:    2013477          XT-PIC  xirc2ps_cs
  5:          0          XT-PIC  usb-uhci
  8:          1          XT-PIC  rtc
 10:          4          XT-PIC  i82365
 11:    2188569          XT-PIC  i82365, cs46xx
 12:    1555382          XT-PIC  PS/2 Mouse
 14:     872963          XT-PIC  ide0
 15:          3          XT-PIC  ide1

and the driver code certainly requests IRQ 12 for the PS/2 mouse
when it's configured.
