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? The phase is steady with the OFFB.

Is it possible that the lcd and crt *have to be* on different
controllers? 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 :)
