Unless somebody else posted it too, that would be me. And I now realise that it was based on your suggestion (on debian-powerpc) a year back! Owen asked: How was it using OFFB?

From what I understand, OF and OSX set it up that way but we don't. As I have no documentation, this is just a conjecture. Still I would like to do just that. But I am constrained by the lack of documentation. Pointers anybody? Maybe people who desire a dual-head would like to help :) regards, -manuj ** Sent via the linuxppc-dev mail list.
