Help regarding epox 8hda3+ mobo

Hi List.
I'm new to this list but I hope I have prepared as best as I can. I have a epox 8hda3+ motherboard with a 3000+ amd64. This is a desktop machine, but nevertheless I would like to "cool'n quiet" it. Searching through the archives I found nothing regarding this board but managed to pinpoint the problem to
dmesg:
powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.00.09b) acpi_processor-0973 [32] acpi_processor_get_per: Error evaluating _PSS
powernow-k8: BIOS error - no PSB

Oookay. From reading the list archives I saw that version 1.00.09b is rather old-ish compared to what's in the list ("version 1.20.08b - March 20, 2004"). As I am not really a kernel hacker, what do I do? I think I have to try|use the powernow-k8-acpi driver, but how do I make this? I use a kernel.org vanilla kernel right now. 2.6.7-rc2 to be precise. I just looked through the 2.6.7-rc3-mm1 patch, but in there is nothing regarding powernow. Is there some patch repository somewhere? Tracking all those patches to patches is a little hard for me...
Thanks in advance!
Cheers
Robos
