I know it says grub-pc only, but all mine are uncommented. And, all mine are on
UEFI installations. All my legacy BIOS installations boot from a custom partition
with Grub Legacy, which is used to boot every installation on the disk. It may be
that what it really means is: not arm*, not sparc, not mips, not ppc....

Mine all are GRUB_GFXMODE="auto", but I have no AMD anything newer than about 6
years old.

I think what you can do is create /etc/grub.d/05_do-text containing:

	cat <<EOF
	  set textmode=true
	  terminal_output console
	EOF

It may be sufficient with only the first of the two. Textmode can be made optional
via hotkey:

	cat <<EOF
	hiddenentry 'Text mode' --hotkey 't' {
	  set textmode=true
	  terminal_output console
	}
	EOF

Evolution as taught in public schools, like religion,
