[Q]Ethernet problem on Walnut ref board(PPC405GP) using Kernel 2.6

[장형욱]

I got problems to activate ethernet on Walnut ref board(PPC405GP) using Linux kernel v. 2.6.x

In linuxppc_2_4_devel(http://www.denx.de) environment, it works fine and
the ethernet is recognized from menuconfig setting below.
Network device support --->
  On-chip net devices --->
    [*] IBM on-chip ethernet (which is ported by montavista)
the source directory is drivers/net/ibm_emac/*

BUT in linux kernel 2.6.5, there is no source included(drivers/net/ibm_emac) and
no menuconfig option to select '[*] IBM on-chip ethernet '

Is there other way to activate ethernet on Walnut without using the above setting in v.2.4
Do I have to any extra work to make the ethernet be working in kernel 2.6 ?? please help me...

Thanks in advance.

booting messages is as follows...
