Hello, Sir(ervery one):
I modified linux-2.6.20.11/drivers/net/Kconfig, just let it build driver for cs89x0, but resulted in worse outcomes.

# # Ethernet #
config CS89x0 tristate "CS89x0 support"
#depends on NET_PCI && (ISA || MACH_IXDP2351 || ARCH_IXDP2X01 || ARCH_PNX010X) depends on NET_ETHERNET
---help--- Support for CS89x0 chipset based Ethernet cards. If you have a network (Ethernet) card of this type, say Y and read the Ethernet-HOWTO, available from http://www.tldp.org/docs.html#howto as well as file:Documentation/networking/cs89x0.txt.
To compile this driver as a module, choose M here and read file:Documentation/networking/net-modules.txt. The module will be called cs89x0.
