Yes. I _PSS was added long before 3.a. As to whether or not the _PSS are valid or why we are having trouble digesting them, I can't say unless I can see a dump of them. Is is possible for you to do that? >>>>> 2 - The BIOS is not returning valid _PSS objects. >>>>> >>>>> The first is easy to check for. >>>>> >>>>> The second usually requires dumping the ACPI tables with a utility like >>>>> iasl and then inspecting the output to see what the _PSS definitions >>>>> look like.
