Hmm, if I sed:
	s/KS8721/DM9161/g
and
	s/ks8721/dm9161/g

on your files I find almost no change with regard to the original
version, except:

#define PHY_ADDRESS (1<<5)

and a #if 0 commenting out a bit of the initialisation sequence...

This makes me think it may only be a PHY_ADDRESS issue: what happens if
you change in cpu/arm926ejs/at91sam9/ether.c :

macb_eth_initialize(0, (void *)AT91_BASE_EMAC, 0x00);

to

macb_eth_initialize(0, (void *)AT91_BASE_EMAC, 1<<5);

Stelian.
