So, I've now tested it against 6.5.0-3-amd64 and the problem remains. 
It's not related to any of your "mistakes" :-)

You need to specify ibt=off to kernel at boot time for the older nvidia 
modules to work. Since the kernel has this protection enabled by 
default, it will have to be disabled until such time as nvidia bothers 
to update/recompile these older drivers like they did the recent ones.
