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. -- Eugene
