In one of the boxes I have there is an option in the bios where I can enable 
Intel Enhanced SpeedStep Technology. If I enable this to disabled in the bios 
then I get the same results as you are seeing. If I enable this in the bios then 
I get no errors but the processor speed doesnt change according to chkfreq from 
acpi_ppc http://www.spa.is.uec.ac.jp/~nfukuda/software/
Did you check the bios for this option?
Another thing is that when I enable it from bios the cpufreq finds the processor 
to be 1500mhz (3000mhz in reality).

You said you have an Athlon X2 box. Did you download 
http://www.spa.is.uec.ac.jp/~nfukuda/software/ and tried the chkfreq program 
which comes out with it to see if powerd is actually working? Because all I know 
is that you might be thinking that it is working but it might not be working at 
all. (I think acpi_ppc doesnt support dual core processors but chkfreq should 
give reliable results)

Thanks,
