Newer kernel do that to make sure both heads are properly POSTed on all cards, but that results in OF setting the card in 2 split heads mode causing the simple tweak used by m3mirror to fail. I'm afraid I won't fix this, we really need real support for the second head for mirroring. Ben. ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
