As I pointed out they may use _DDN which will be part of the DSDT independenly of the ACPICA version (`iasl` may add comments on the devices it knows) or any other ACPI tools. The cons of this is the unused bulk in the ACPI tables, meaning wasted space in firmware. -- With Best Regards, Andy Shevchenko
