It goes back to ICH7 for the PCIe support. That also includes models used
as plugin PCIe devices. I dont remember if ICH6 erra devices were PCI or
PCIe. I'll leave that part for Auke.

I think making e1000new ICH9-and-newer isn't really the best place to
split it. The Windows e1000 driver got split on the PCI->PCIe
transition, something that clearly delineated what nics one driver
supported, and the other. There's no real technical reason for
splitting now other than "this was when e1000old collapsed under its
own weight".
The PCIe adapters are also the first ones to support multiple queues
IIRC, maybe that would be an another actual technical reason to split
it there?
Can knowledgeable people characterize the PCIe adapters somehow? Is
that "ICH8-era and later", or does it go back further than that?
ich7 and 6 are sold with various on-board NICs, often pre-pcie e1000 silicon
like 82547 and 82546. Some newer models (lenovo, toshiba) laptops pack 82573,
but basically ich chipsets before ich8 did not have an in-chipset MAC, so they
are irrelevant for this story.
only es2lan, ich8 and ich9 have true on-board MAC's.
