The oklinux configuration explicitly removed most/all network driver support 
from the linux kernel. So you need to change the .config of your oklinux to 
add support for the network device you are targeting. Then, recompile the all 
thing.

Now in your case with 2 oklinux running on the same hardware (it seems this is 
what you are targeting), I guess you could run into some trouble if both 
instances try to take control of the single network device. I don't think you 
will succeed in making the 2 oklinux speak together through the ethernet 
device if they are on the same gumstix ... You should use the OKL4 IPC for 
this kind of thing.

There might be a way to tell OKL4 to forbid hardware access for one of the 
oklinux instance in order to give exclusive access to the device to the other 
oklinux. At least this would allow one of the oklinux to speak to the outer 
world.
