[Nouveau] report almost a success with Randr1.2 on NV50

[Hervé Cauwelier]

Hi,

I've seen many patches about randr so I decided to give it another try.

I've hotplugged a VGA monitor on my laptop and it detected all
resolutions but the native one. I was able to move either screen on the
left or on the right. Gnome was trying its best to place its panels on
the bottom-right most corners.

The only two issues are this native resolution not detected, and Gnome
not placing the panels where I expected. I was used to the intel driver
placing them on the main screen, and leaving the extra screen empty.

Yet I was very happy and I wanted to share my joy!

This is a 8400M GS with the master branch of nouveau and drm.

Regards,

Hervé
