Bug#976056: nvidia-legacy-340xx-driver: Fails to build with kernel 5.9.11 (package linux-image-5.9.0-4-amd64)

[Paolo Inaudi]

@jim_p Is it possible for you to avoid putting all system information 
and Xorg logs in every message?
It makes the thread very difficult to follow on the online bug tracker.

I too rolled back to linux-image-5.9.0-3-amd64 which works, hope it 
won't be my very last kernel version.
