OK. I used the kernel that had your 2 patches anyway, as I didn't have another
APIC-capable kernel without Alan's test patch on hand. Booted with your
options.

This time, the mouse was working OK after bootup, but unplugging and
replugging it in cause the "irq 21: nobody cared" message and IRQ21 was
disabled again.
