Thanks to Gerd, there is now a patch for NVIDIA driver 495.44 and Kernel 5.16-rc1, which can be found under the comments on my previous article: https://rglinuxtech.com/?p=2974
Of course, take care to cut/paste in text mode, as html will ruin the formatting etc..
I have applied this, and 495.44 now appears to compile/load/run OK, with kernel 5.16-rc1..
