Code inspection of smc91111.c shows that the driver is reading the MAC 
address from the ROM, if it detects one.

I did not snoop the line but the link lights are dead.  I doubt sniffing 
packets would reveal much else.

The 'ethaddr' environment variable would override any other MAC address, 
real or bunk.  If the chip is in a reset state then all bets are off as 
to the values being returned from the ROM.  This could explain why the 
MAC address from the ROM is bad. 
The chip looks dead.
Anyone know if there are certain FPGA settings that might need to be set 
on the Integrator/CP with ARM926EJS core module to wake up the LAN chip?

I applied the patch but the compiler still puked when compiling 
cpu/arm926ejs/start.S.  It complained:

cc1: invalid option 'abi=apcs-gnu'

So I changed the cpu/arm926ejs/config.mk:

+++ config.mk.orig      2005-12-21 15:47:45.421844207 -0800

This got it to compile but 1.1.4 exhibits the same LAN problem.
