[SMP, USB] UHCI interrupt wrongly routed?

Hello
I guess, it is not a USB problem, really, it just appeared with USB. On a
2-way running 2.6.9 the onboard UHCI device is configured to IRQ 9 via
XT-PIC???

21: 2576 0 IO-APIC-level sym53c8xx
NMI: 0 0
LOC: 587726 587988
ERR: 0
MIS: 0
Non-surprisingly, it doesn't work. Below is a complete dmesg (I first
connected the card-reader to an ohci / ehci PCI board, and then
re-connected it to an on-board UHCI port.
Thanks
Guennadi
