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.
