Fun in dmesg:

    --- dmesg-2.6.12-rc4
    +++ dmesg-2.6.12-rc4-mm1

    -PNP: PS/2 Controller [PNP0303:PS2K] at 0x60,0x64 irq 10	    <===
    +PNP: PS/2 controller doesn't have AUX irq; using default 0xc
     PNP: PS/2 Controller [PNP0303:PS2K] at 0x60,0x64 irq 112	    <======
    +serio: i8042 AUX port at 0x60,0x64 irq 12
     serio: i8042 KBD port at 0x60,0x64 irq 1			    <===

I never realized "irq 10" meant "KBD irq 1 and you don't have AUX irq". In
2.6.12-rc4-mm1 "irq 112" means "KBD irq 1 and AUX irq 12 (now assigned by
default)".
