So, what's the way to proceed here? Can we add the boot parameter when
the legacy kernel module is to be loaded on newer Intel processors?
I probably made a mistake while backporting some non-trivial changes for
supporting recent kernels. With the availability of 470.223.02 I could
verify my backport against the upstream version, drop a lot of unneeded
bits and fix some discrepancies...
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.
