I think it's a little over-engineered ... why not simply:

config E1000_SUPPORT
bool "Intel(R) PRO/1000 Gigabit Ethernet support"
depends on PCI

config E1000
depends on E1000_SUPPORT
tristate "E1000 PCI support"
help
Include support for Conventional PCI devices. This includes
chips built into motherboards ... blah blah, if unsure say "Y"
or "M"

config E1000E
depends on E1000_SUPPORT
tristate "E1000 PCI Express support"
help
Include support for PCI Express devices. This includes chips
built into motherboards such as ICH9 ... blah blah, if unsure
say "Y" or "M".

and get rid of the PCIE() macros from the e1000 driver. While it does
allow someone like Ingo to create a E1000=y and E1000E=m situation
(which won't bind to an ethernet card that E1000 used to), having the
E1000_SUPPORT symbol means that oldconfig will stop and ask you which
hopefully makes it obvious enough that things have changed here and you
need to pay attention.
