I'm not sure about 2.6.12-rc1, but you can try GIT tree/patches at 
http://kernel.ebshome.net. 

Hint: you can assume that in addition to emac_3-2.6-28.diff, there are 
also emac_3-2.6-NN.diff (NN < 28) on my website which were made for 
earlier kernel versions :).

Alternatively, you can backport all relevant stuff from current 2.6 or 
you can pay someone to do this for you.
