I've tested the issue on kernels 3.2.1 - 3.2.9.
Comment 3 Zhang Rui 2012-03-19 08:27:26 UTC 
This is a BIOS bug.

\TST0 and \PST0 are used by _TPC and _PPC, but they are not defined, neither in DSDT, nor in SSDT.

Please check if there is BIOS update for this machine. :)

I have Asrock X79 Extreme9 motherboard: http://www.asrock.com/mb/overview.asp?Model=X79%20Extreme9&cat=Specifications

I have latest (at the current moment) BIOS - 2.00 from the download section: http://www.asrock.com/mb/download.asp?Model=X79%20Extreme9&o=BIOS

I have not understand middle of your post cause I'm not programmer. I'm ready to write to asrock support. Do you think that information in this bug and comments is enough for them?

Your machine will probably work fine,
even though the _TPC and _PPC in ACPI BIOS are broken.

One could argue that Linux should silently ignore this BIOS bug,
like other OS's do, rather than printing messages...

In any case, yes, the info here is enough to tell the vendor
what they did wrong, assuming that you can get through to
their ACPI BIOS engineers.
