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.
