Okay, I decompiled the SSDT table by hand (small table anyway), find it 
attached (really!). It doates indeed define the _PPC field and two other 
names, which make little sense to me.

Which leads to my next question: I thought leading underscore names were 
reserved by the ACPI spec. ACPI 1.0 doesn't define the names, and ACPI 
2.0 defines them differently. Can this lead to problems with the Linux 
ACPI implementation making assumptions about ACPI 1.0 code with 2.0 
extensions?
