Hmm, why you are hopping through all these loops?I'd just keep the existing pci_device_{save,load} functions. load anyway for backward compatibility. save also for devices not yet converted to vmstate. I think alot of the complex stuff you are building up here isn't needed then, unless I missed something ...
Beside that we'll have to think about how to handle versioning of structs. Do we want vmstate_pci_device (and all others) have its own version? Probably makes sense. Handling this should go into the generic code then and not be hacked into each structure using VMSTATE_INT32_LE().
cheers, Gerd
