You may have to delay 6/8 as well, since the controllers are PCI devices. Writing the new code shouldn't take too long, though.
Is there a good way to iterate through all PCI devices in a particular slot, or should it be done by going through all PCI devices and ignoring those in other slots? Calling pci_get_slot() multiple times doesn't look very efficient.

Then when you install the test kernel, mkinitrd should build a corresponding initramfs image with the modified drivers, right? Otherwise there would be a version mismatch error when the init code tried to load the old drivers into the new kernel.
If nothing else works, you can simply unload the standard uhci-hcd, ohci-hcd, and ehci-hcd drivers and then modprobe the modified versions before starting the hibernation.
