I don't know how to do this.

But I do know how to set the duplex switch for a 3c59x ethernet card.
This is from http://www.scyld.com/network/vortex.html

In your /etc/modules.conf file, you should have:

   alias eth0 3c59x
   options eth0 full_duplex=1

and then reboot.  (You could also insmod the module, but you'd first have
to go to single-user, rmmod the module, and insmod it with the full_duplex
option.  Might as well edit modules.conf and reboot to make sure it will 
take the next time you reboot.)

I had to do this because I connect to an old switch which doesn't 
auto-negotiate the duplex setting.
