Yep, it's all one's.

And once "s2ram" (without parameter) is executed, there's no way to
restore back the console in text-mode even using "s2ram --force
--acpi_sleep 1 --vbe_mode" until a "suspend-to-disk" or a reboot.

"s2ram --force --acpi_sleep 1 --vbe_mode"  will only work on
non-messed-up-console.

Thanks,
Jeff.
