As far as I can see, usb_hcd_pci_probe() is using pci_enable_device()
correctly, so "pci=routeirq" shouldn't make a difference.  However,
I do see a similar ohci_hcd initialization failure on my DL360
(my failure occurs both with and without "pci=routeirq").

My device worked correctly on 2.6.9-rc1-mm4 and is broken in 2.6.9-rc2-mm1.

My errors look like this:
 ACPI: PCI interrupt 0000:00:0f.2[A] -> GSI 10 (level, low) -> IRQ 10
 ohci_hcd 0000:00:0f.2: ServerWorks OSB4/CSB5 OHCI USB Controller
 ohci_hcd 0000:00:0f.2: irq 10, pci mem 0xf5e70000
