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().
