Okay, so I spend a few weeks with F96-CE_4 to get it to work on my old desktop with an NVidia GT1030 pcie graphics card.
Eventually had to change to an earlier kernel to get KMS with Nouveau drivers (ended up using huge-5.4.86-slacko64 kernel).
Tried many kernel versions 6 plus from Rockedge's repository but all failed to do KMS with Nouveau, so userspace driver always stuck on VESA (possibly an ACPI issue1).
Anyway I thought I should try BookwormPup since it is Debian based, which from what I have read is more a more "conservative" distro that is less likely to break operations.
Now wrt KMS, BookwormPup with Kernel 6.1.94 works OOTB for me, and even better, I can use it with either the Kernel Modesetting driver or the Nouveau driver (jippy).
So a kind of obvious question, but I am still asking because I am still a linux Noob even after the above sucessfull result with F96-CE_4 (very nice OS):
Is the Debian kernel ,its modules, and system firmwares, compiled with more options or hardware inclusivities than the Ubuntu or Slacko kernel?
Or is kernel 6.1.94 the same kernel 6.1.94 regardless of what distro it is facilitating with only kernel modules or firmwares being different?
