no CPU frequency scaling on AMD Sempron 2100

I have 9.0-RC3 installed on an HP Thin Client that has a Mobile AMD Sempron(tm) Processor 2100+. I am trying to get cpufreq and powerd to manage the frequency of the processor, but I'm not having any luck. Here's some lines from dmesg:

Any suggestions on how to get CPU frequency management working?
 
Was the frequency scaling working before with another version of FreeBSD or OS?
Have you checked the BIOS (enable Cool&Quiet or Powernow)? (well should be on on default)
And please post the your output of:

[cmd=]sysctl dev | grep freq [/cmd]
 
I haven't put any other OS on this box so i don't know if it was working before or not.

There are no options in the BIOS for Powernow or Cool'N'Quiet.

Code: 
sysctl dev | grep freq
returns nothing.
 
That's interesting. WikiPedia says it does not support PowerNow, but AMD docs do.

My goal here is to get the heat output down. But if I can't, then I can't, so I won't.

Thanks guys!
