I'm getting the following error when trying to load the powernow-k8 kernel

 % modprobe powernow-k8
 FATAL: Error inserting powernow_k8 (/lib/modules/2.6.23-grml/kernel/arch/i386/kernel/cpu/cpufreq/powernow-k8.ko): No such device

 % dmesg | tail -2
 powernow-k8: Found 1 AMD Athlon(tm) 64 Processor 2800+ processors (1 cpu cores) (version 2.00.00)
 powernow-k8: BIOS error - no PSB or ACPI _PSS objects

I think my BIOS supports the AMD PowerNow! technology, why I'm still
getting the above? Is there anything on the software side that I'm missing?

My box:
