I don't think it must be as-is (i.e. replacing e1000 for all HW) but
don't throw away all the work they've done in architecting the driver
to cleanly handle multiple chip generations.

How about:

1) Considering e1000new's current design, but for ICH9 only
2) test test test
3) Sometime in the future, considering incrementally moving previous
PCIe generations' support from e1000 to e1000new (like I initially
wanted, since that at least means there would be some technical reason
for where the split occurs :-)
