Jim,
  Try looking in /usr/src/linux/Documentation, the kernel documentation
directory.  More specifically, the networking directory.  Most cards have
documentation that shows how to change duplex settings.  I don't know about
recompiling, its usually just a parameter passed when you load the module.
If its a 3com card, there are some nice utils written by Donald Becker that
can change the settings directly on the card, though I like the module
params myself.

http://www.scyld.com/network/

is the linux networking site maintained by Donald Becker.  Its a pretty good
place to start with tons of very useful documentation and usuage
instructions for a lot of the linux network cards.  i found all the duplex
settings for my 3com cards on this site, they work great!  i learned that
forcing the card to 100full, if supported by the card and switch, works
better than autonegotiation.  your mileage may vary though.  good luck!

Jason
