I think it would be even more important to just have driver writers test a
device-per-device "suspend, trash the PCI state, resume" sequence, so that
individual driver writers can test _their_ particular driver (and never
mind the tree nature - most of the drivers are "leaf nodes").

But yeah, doing a full-tree version of the same is probably also useful. I
did that (as a total hack) for some of the mac mini testing, by just
commenting out the "->enter" stage, which obviously also avoids a lot of
other things).
