Description of problem:
I've seen this in rawhide for a little while now and it appears that
it's also in Phoebe. The default USB host controller driver will not
load correctly. This is what it says on bootup:
init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters,
including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
And then in /var/log/messages:
Dec 26 23:30:11 oveja kernel: PCI: Found IRQ 10 for device 00:1d.7
Dec 26 23:30:11 oveja kernel: hcd.c: ehci-hcd @ 00:1d.7, Intel Corp.

Of course devices that used to work in 8.0 don't work. I would assume
it's due to this problem.
This is on an Intel 845GBV motherboard.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot system
2. ehci-hcd fails to load
Actual Results: ehci-hcd fails to load and USB devices do not work.
Expected Results: ehci-hcd loads and USB devices work as expected.
Well...I got it to work! sort of.... the ACPI stuff didn't do it - but
I've left it in. I got the latest ehci-hcd patches from bitkeeper on
ftp.kernel.org and applied them. I'm pretty sure that's what fixed it -
although in the process I've also update the hotplug rpms and added some
patches to usbdevio and usb-uhci. So, I'm not sure what actually fixed
it. :-( I do know that after I applied the ehci-hcd patches all the
errors went away - but it still didn't find my USB device (camera).
So here's the interesting part. When I installed the latest hotplug
rpms, it adds a startup script that pretty much does the same USB module
loads that the stock RH scripts do. However if I do a stop and restart
using this script, voila! All of a sudden it sees hardware attached to
the bus. The only difference that I can see is the order in which
things are done. RedHat loads usbcore and then the controller modules
(ehci-hcd, usb-uhci) and then mounts the usbfs. The hotplug rpms load
usbcore, mount usbfs and *then* load the HCDs.... Go figure.

The recent 2.4.21-pre3 fixes this issue on the Intel motherboards.
Please pick up the recent patches.
yeah they should be in rawhide already
