This method worked pretty well for me (Lenovo Yoga 7i) with kernal 5.8.0-53-generic #60,
After update to 5.8.0-55 the S3 is not visible.

when I'm grepping for ACPI I see that the overwriting of the acpi DST table is done very early in the dmesg log, whereas in 0.55 it's done later, maybe that's an hint.
