another note: in case the resume fails, the ACPI code wasn't able to read out the GPUs state as well, so most likely all values are garbage and simple contain -1, which would mean that LNKS will never be below 0x07 anyway.
So everything I was reading out via ACPI returned 0xffff, but maybe that's just the case for me (Dell XPS 9560).
