According to the documentation I could find, weak symbols were present 
in gcc 3.4.1.  Are you sure you're using them properly?  Due to the way 
linking is performed in U-boot, any weak symbol overrides need to be in 
source files that have strongly linked symbols.  You'll see that all 
implementations of cpu_eth_init() and board_eth_init() are in files that 
already contain stuff that is sure to be linked.

If you're really unable to make this change due to your tools, I'm not 
opposed to pulling this driver in.  I just want to know that you intend 
to port all the Xilinx drivers over some time in the near future.
