The thing that makes this all confusing/annoying is that when I was using a

Try making your own kernel with the needed drivers built-in and the
ordering should start to get semi-predictable, but then it might not be
because the kernel, and userspace, and your hardware, do not make any
guarantees of this AT ALL.
So you really are on your own here, good luck!
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.
