Bjorn, Linux kernel devs,
when booting with a recent kernel (2.6.9-rc2-mm2), usb_ohci fails to
initialize the USB bus and no USB device will work at that point.
Adding pci=routeirq fixed the problem.
I believe this has been working with earlier kernels, but I don't use
USB often enough to remember.
The PC is an Compaq (HP) Presario 2100Z notebook.
Here's a diff of the dmesg output of two boots with and without pci=routeirq:

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:

Can you try this whitespace-damaged patch to see whether you're
seeing the same issue I was? If this patch fixes it, please post
the "lspci -n" output for your USB controller, so we can add a
quirk for it.

Yes, this patch fixes the problem.
I've submitted a different patch based on the testing results (Email
subject: [PATCH] ohci_hcd: ALi USB M5237 host controller init quirk),
which enables the quirk for my USB controller. That hopefully will
save you some work.
The lspci -n output (for reference) is:

Which equals:
