The reason it says this is that it is embedded in the script 
grub-mkconfig.  It overwrites the grub.cfg, but if you don't run that 
and only do manual edits, then it's not there.  The problem is that many 
distros think they know more than the user (usually true, but not 
always) and always run grub-mkconfig every time the they update the 
kernel whether you want that or not.

I believe that's hardware dependent.

That's probably because the kernel is configured to use a framebuffer by 
default.  It's not a grub issue at that point.

To disable the freamebuffer, see the advice in 
https://wiki.ubuntu.com/FrameBuffer

Keep a backup of /boot/grub/grub.cfg and restore it after upgrading the 
kernel.  Then edit the file to add the new kernel.
