Yeah, I get the picture.  I traced the kernel code and like even with drivers as 
builtin we have the possibility of ordering issues when pci_call_probe calls 
local_pci_probe via a workqueue.  We may have just gotten lucky previously.

I want to move to position-based naming eventually, it was just not really a 
good time.

Thanks for the comments, everyone.
