Ok. Let's restate it in my own words to make sure I understood you correctly.

But first, let me say that I already have tried 4.4.0 without proprietary
firmware. To this end I omitted nouveau.config="NvGrUseFw=1". I experienced the
same crash with freeze while scrolling a LibreOffice Writer document. So bad
news the bug is still there.

Now, I wanted to check if 4.4.0 with proprietary firmware works without
crashing. For this purpose you want me to rename

nouveau/fuc409c -> nvidia/fecs_inst
nouveau/fuc409d -> nvidia/fecs_data
nouveau/fuc41ac -> nvidia/gpccs_inst
nouveau/fuc41ad -> nvidia/gpccs_data

These are essentially the same files but with a different path and name. Then I
change

CONFIG_CMDLINE="nouveau.config=\"NvGrUseFw=1\""
CONFIG_FIRMWARE_IN_KERNEL=y
CONFIG_EXTRA_FIRMWARE="nvidia/fecs_inst nvidia/fecs_data nvidia/gpccs_inst
nvidia/gpccs_data"
CONFIG_EXTRA_FIRMWARE_DIR="firmware"

After re-compilation I should have a new kernel that uses the proprietary fw
and I should be able to check if the crash with freeze is still there or not.
