yes, it says that, but please have a look at the DualHeadSetup application
source if it doesn't use the same protocol after all. Have you confirmed
that? If it does not use the same protocol (ie same additional flags
defined for the display_mode flags), then your next option is to change the
nvidia driver to do use the same protocol. :-)
