Ok, then I must have missed something when building the system. What do 
I look for in the LFS book to build the right ethernet driver?

Well, when I brought up LFS last year, it was dhcp that actually figured 
out the proper stuff for ethernet. I no longer remember exactly what worked.

My problem here is that I'm so new to the guts of linux that I often 
don't even know what to look for when a problem arises.

Ok, I looked it up but am not much the wiser. :-)

This reminds me somewhat of the documentation provided by Cadence Design 
Systems for its Integrated Circuit design software, which I use every 
day at work. They have their own programming language called SKILL, a 
hybrid of C, Lisp and who knows what else? One part of the documentation 
might refer to a function "foo_The_Bar", which you can find a 
description of in a reference manual. The descriptions are often of the 
form:

foo_The_Bar( t_text ) -> n_number
This function foos the bar.
...

Distinctly unhelpful if you don't already know what "foo" and "bar" are 
and why you need to bother knowing. :-)
