As pointed out in my previous mail, http://www.coreboot.org/pipermail/coreboot/2009-June/050342.html I flashed the bios. Unfortunately, the thermal problem did not go away: /var/log/kern.log still contains this message: Jun 30 08:37:56 bcipc038 kernel: [ 4.123091] powernow-k8: Found 1 AMD Phenom(tm) 9750 Quad-Core Processor processors (4 cpu cores) (version 2.20.00) Jun 30 08:37:56 bcipc038 kernel: [ 4.123109] [Firmware Bug]: powernow-k8: Your BIOS does not provide ACPI _PSS objects in a way that Linux understands.

Please report this to the Linux ACPI maintainers and complain to your BIOS vendor. And when running the test program, the computer shuts down after about 5 minutes. kern.log contains this message.

The reduction of the shutdown time from 50 min to 5 min makes the situation even worse.
