When I boot my computer with nouveau and KMS, I get a black screen after UDEV starts on Debian Testing. I've attached some logs.

Did this ever work? Looks like the internal LVDS screen is detected just fine, resolutions are all there, no errors. Is it right that the internal screen is 1920x1200?
Can you confirm that the problem still exists with 3.16-rc5?
I will compile and test 3.16-rc5
I've only ever used Nvidia's drivers on this particular computer so far. The screen is 1920x1200. It is an old Dell XPS 1730.
It is the same with 3.16-rc5

Xorg log on 3.16-rc5
kernel 3.18 has the same issue
This is still not working on Kernel 4.2. But during this test I had the laptop connected to a DVI output. And the DVI output worked great. So it seems this is not working for the LVDS only, which has the black light on but remains blank/black.
I noticed on a Google search that there had been blank screen issues on pre-nv50 drivers: http://patchwork.ozlabs.org/patch/215168/
I wonder if this is something that exists on my card as well. I was glad to see the display working on the DVI output, but I am hoping to have this working on LVDS at some point.
A random thing to try -- boot with
(It appears that you have 2 GPUs... perhaps they're both connected to the LVDS somehow, and the second one turns it off?)

I tried this. And it was still a black/blank screen. However maybe you are onto something as this is a laptop with a Nvidia 8700m setup as an sli card. Though with the proprietary driver and with Windows it has no issue booting up properly. However I find windows really slow and would like to switch to nouveau to future proof my laptop since I am betting Nvidia won't develop a Wayland driver for this card.
