powernow-k8 trouble on FC2T3



Hello,

	I've got a laptop (Hypersonic model Aviator AX6 with Athlon 64)  
running Fedora Core 2 Test 3 (kernel 2.6.5-1.327) and I was interested in
using CPU frequency scaling since /proc/cpuinfo shows my CPU at its lower
speed.  So I rebuilt a custom kernel with the CPU_FREQ options selected.  
When I boot using the new kernel and then add the powernow-k8 module to
the kernel using

> modprobe powernow-k8

I see in /var/log/messages the lines

powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.00.08b)
powernow-k8: BIOS error: numpst must be 1

and as far as I can tell, nothing else happens.

Am I doing something wrong, or is there a fix for this issue?

Thanks for any help.

Here are some CPUFREQ-related lines from my custom kernel .config file:
