I don't know the technical details. But i tried it myself, came up with
the same error message as you and filed a bug, because I read the doc
and understood the driver is meant to support DH. But Bill Nottingham
told me, the driver is broken in some way, does definitely not support
dual head on a single card, and nobody knows how to fix it. Only nvidia
people could help out.
