Hi. Many people know that GTX660 (gk106, nve06) is working well only with
firmware blobs. (see i.e. https://bugs.freedesktop.org/show_bug.cgi?id=93629)
I had using them in my old Gentoo Hardened with kernel 4.4.8 and all was fine,
video card worked very well with 4 .bin files in /lib/firmware/nvidia/gk106

fecs_inst.bin
fecs_data.bin
gpccs_inst.bin
gpccs_data.bin

Now I installed a new system from scratch on same computer. Used **exactly same
kernel config** (it means it is valid for all *FIRMWARE* values), but newer
kernel version 4.7.10-r1. I put same firmware files into
/lib/firmware/nvidia/gk106, put nouveau.config="NvGrUseFw=1" in grub kernel
line, but it is not loading, I can't see line in `dmesg | grep nouveau` gr:
using external firmware, as it was in my old 4.4.8 setup. 

After that, I tried to copy these blobs to old naming space,
/lib/firmware/nouveau/fuc*, tried to include them in kernel directly, tried to
include it in initramfs, nothing helps. It doesn't run.
My current dmesg | grep nouveau:

So it contains line 'gr: using external firmware'

Please help me load these blobs back to my new system to work without freezes.

Thanks a lot
