The "examples/turn_off_gpu.sh" script (previously test_off.sh) from
https://github.com/mkottman/acpi_call returns "failed" for all cases,
but the kernel logs "kernel: acpi_call: Cannot get handle: Error:
AE_NOT_FOUND" for all cases, so probably the acpi_call kernel module is
outdated (not updated since 2013).
