Once reading the ACPI spec I noticed that ACPI supports this feature so it is qute nice to implement it, since this will prevent resume from disk what hardware was changed. But.. how many bioses are broken regarding this feature....
If they are broken though, how likely is it they'll have a changing signature? I'd expect the most likely broken case is they just don't calculate it at all and leave it constant. johannes
