ACPI screwing up USB ehci_hcd with kernel 2.6.16.18

I had a problem with ACPI IRQ routing messing up the USB ehci module.
I have to disable the irq routing with apci=noirq in the bootloader config in
order to use the ehci module.

Failing to do so results in :
usb 5-1: new high speed USB device using ehci_hcd and address 3
ehci_hcd 0000:00:10.4: Unlink after no-IRQ? Controller is probably using the
wrong IRQ.

System :
Kernel 2.6.16.18
Chipset VIA KT400A
