Ok, I am now trying this:

/usr/src/linux> grep FIRMWARE /usr/src/linux/.config
CONFIG_FIRMWARE_MEMMAP=y
# CONFIG_GOOGLE_FIRMWARE is not set
CONFIG_PREVENT_FIRMWARE_BUILD=y
CONFIG_EXTRA_FIRMWARE="nvidia/gp107/gr/sw_nonctx.bin"
# CONFIG_CYPRESS_FIRMWARE is not set
# CONFIG_DRM_LOAD_EDID_FIRMWARE is not set
# CONFIG_FIRMWARE_EDID is not set
# CONFIG_TEST_FIRMWARE is not set

Best

There's a lot more firmware files than that ... everything in the
gp107 directory. Also this would only be necessary if nouveau is built
into the kernel. The files just have to be available whenever nouveau
is loaded -- if it's built in, that means the firmware has to be baked
into the kernel too. If it's loaded from initrd, that means the
firmware has to be in initrd. If it's loaded after boot, then the
firmware has to be available after boot.

Thank you, Ilia

For the time being I got it working by removing all nouveau selections
in "make menuconfig" and by emerging
"x11-drivers/nvidia-drivers"
Version 440.82.

Back on the latest Linux Kernel. Feels great ;).
