It shows the blacklisting of the nouveau drivers in there. Is that a
change with the 6.0.5 kernel, prior to that kernel they were always in
/etc/default/grub?
Just looking at grub.cfg I have now found that while I thought I was
boot off the 6.0.5 kernel, I hadn't actually run grub2-mkconfig to
update grub.cfg for the new kernel. I have run that now and because
/etc/default/grub no longer has the nouveau blacklisting statements they
are not supplied on the kernel line in grub.cfg for any kernels it's set
up to boot from. From below /proc/cmdline has also not been updated for
the 6.0.5 kernel either, I'll see what it shows when I get a chance to
boot off that kernel.
cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-5.19.16-200.fc36.x86_64
root=UUID=ba36dde9-5bf1-4140-89e7-b82ee1fe7cf9 ro
rootflags=subvol=Fedora_root rhgb quiet rd.driver.blacklist=nouveau
modprobe.blacklist=nouveau nvidia-drm.modeset=1
