2.6.1 - IRQ routing regression on Abit VP6

[Ian Pilcher]

2.6.0 works fine on this hardware, including the twitchy built-in USB
controllers.

Loading the uhci-hcd module on 2.6.1 gives me the following:

drivers/usb/core/usb.c: registered new driver usbfs
drivers/usb/core/usb.c: registered new driver hub

Disabling IRQ #177
usb 1-1: control timeout on ep0out
uhci_hcd 0000:00:07.2: Unlink after no-IRQ?  Different ACPI or APIC 
settings may help.

And so on, until I shut down the system.

The 20031203 ACPI patch fixes the problem.
