The randr-1.2 git branch is no longer used, it has been merged into master. If you want to test your luck with Randr 1.2 functionality, install the driver as usual, using at least xorg-server version 1.3. Add the line
{{{
Option      "Randr12" "true"
}}}
into your xorg.conf in the {{{Section "Device"}}} that calls the Nouveau driver. Do realize that dual head support is in its infancy and probably cannot drive your monitors correctly. See the FeatureMatrix about supported cards.

These issues are no longer valid (certainly not for nv4x cards).

Relies on BIOS (like nv to setup some registers for it) so hotplug may not work - vbetool post is your friend

* NV28 - single head - VGA, DVI (analog + digital)
       - dual head - VGA + analog DVI

Some NV40 can init a second head, there are still some issues with some G70 cards.

On G80 where Randr12 is activated by default, the hotplug is not working.
