pci power management
I think the kernel should put every unclaimed device on the pci bus into D3cold state. It can then be reactivated when a module is loaded. All pci drivers should also put any device it has claimed into D3 if it is unloaded.

Some devices are still used even though they are not claimed by a kernel driver, ie. video cards and PCI/AGP bridges.
