Ingo,

I just changed the mapping for the MPU-401 interrupt to IRQ 10.

So far the only system instability I've noticed was a XFree86
3.9.18 crash last night. When I looked at dmesg, there were
two new messages at the end:

spurious 8259A interrupt: IRQ7
keyboard: Timeout - AT keyboard not present?
