I tried to compile a kernel under 1.1 to include PPP functions.  I
commented out all the ethernet cards since I don't have one on my home
system.  The make complained about missing modules (ether_output,
ether_[add|del]multi, arpt_[keep|prune]), so after some thrashing I
added back a define for "ed0".  The make then built a valid kernel.

It seems non-intuitive to me that I should define an ethernet card
in a system that doesn't have one.  Is this behavior different in
more recent systems?
