We only support people keeping their old configs after they run 'make
oldconfig', right?  At which point they'd be prompted for E1000_SUPPORT.
Presumably they'd think "That's odd.  I'm sure I had that selected
before", then select it.  Then oldconfig skips over CONFIG_E1000 because
it already knows the answer to that one and they're prompted with a
question about PCIe support.  Now something is clearly strange.  Perhaps
they look at the help text at this point and it says to go with 'Y' or
'M' if they're not sure.

That's the most important bit of help texts for me.  Do I want Control
Groups?  Will my machine break if I don't select them?  I have no idea
what a 'process cgroup subsystem' is, and I don't care.  But the help
text tells me I can say "n" and nothing will break.

I quite agree.  I have no idea either.  All I know is that my ICH9 box
didn't work until e1000e was released ;-)
