OK, I'll do that when I'll have a bit more free time, but likely within the 10 next days. Shall I fill the report on this site[1] ?

Re: [Nouveau] Handling GeForce GTX 850M GPU on Arch Linux
Your first reply did also sent it to the mailing list. :-) [1] is indeed the correct site to report the bug, with Product=xorg and Component=Driver/nouveau.
