I had just started to do a 405 EP port of 2.6.11-rc4 based off of the bubinga config. Q2: Assuming yes, to Q1, any advice on how I should proceed, continue on with an OCP port or wait for this new stuff? Q3: How does one stay in the loop on this stuff? With only about 3 messages posted in this group and none in linuxppc-dev I am clearly in the wrong place. I feel like I missed the conversation. Where was it? Best, leb
