That looks like the one, from browsing /usr/src/kernels on my system, in 
drivers/net/tulip/Kconfig:
config DE2104X
         tristate "Early DECchip Tulip (dc2104x) PCI support (EXPERIMENTAL)"
         depends on NET_TULIP && PCI && EXPERIMENTAL
         select CRC32
         ---help---
           This driver is developed for the SMC EtherPower series Ethernet
           cards and also works with cards based on the DECchip
           21040 (Tulip series) chips.  Some LinkSys PCI cards are
           of this type.  (If your card is NOT SMC EtherPower 10/100 PCI
           (smc9332dst), you can also try the driver for "Generic DECchip"
           cards, below.  However, most people with a network card of 
this type
           will say Y here.) Do read the Ethernet-HOWTO, available from
           <http://www.tldp.org/docs.html#howto>.

           To compile this driver as a module, choose M here and read
           <file:Documentation/networking/net-modules.txt>.  The module will
           be called de2104x.


I don't know where you should go from here, perhaps look in 
system-config-network and see what that gives you for options and such.
