The tg3 and e1000 are commonly found in off the shelf dell machines and
similar other OEM boxes.  The reason they were built in was because we
faced no end of users who would build new kernels but not build/install
the new modules and/or the initrd stuff with the modules bundled.  So
they would complain about their build not working on their hardware.

I can respect the goal to keep kernel size down, but at the same time,
we should not trade off a saving of two pages (8k) at the expense of
hundreds of users who assume "defconfig" will boot on their machine.
Maybe we can use CONFIG_EXPERT to our advantage in giving you what you
want and at the same time, not breaking existing users who don't?

Paul.
