Nouveau - Mar 2015 - GM206 support?

My new GTX 960 (GM206, I think) says:

[   10.329351] nouveau ![  DEVICE][0000:09:00.0] unknown Maxwell chipset
[   10.329355] nouveau E[  DEVICE][0000:09:00.0] unknown chipset, 0x126010a1
[   10.329356] nouveau E[     DRM] failed to create 0x00000080, -22
[   10.330129] nouveau: probe of 0000:09:00.0 failed with error -22

Hacking up nouveau so that it treats it like a GM204 doesn't work.
Are there any near-term plans to support this card?

Thanks,
Andy

What happens if you just drop the 0x126 next to the 0x124 in
engine/device/gm100.c ?

I don't know of anyone with the hw... maybe Ben got one? If you're
interested in helping, the kernel logs from the above experiment + an
mmiotrace of the blob drivers (see
https://wiki.ubuntu.com/X/MMIOTracing) + vbios (see
http://nouveau.freedesktop.org/wiki/DumpingVideoBios/).

I assume you're on a recent kernel? You need 3.19 for the GM204 stuff
to work in the first place.

If you have any other things/patches to test just let me know. I'm also 
around in #nouveau

Neither 3.19 nor 4.0-rcsomething works.

I put an mmio trace (X startup and glxgears) and a vbios dump here:
