CPU Frequency scaling with Phenom 9850 on an ASUS M3A

I'm having trouble making this work; the software is Ubuntu Linux,
latest version (8.04, with all updates).

The system reports that no support for CPU Frequency Scaling is
available (the applet does show the CPU running at 2.5GHz at all
times).

I'm guessing it would be a BIOS setting (Ubuntu forums don't
report any "usual suspect" related to software), but I can't find
anything that sounds to me like relevant --- I enabled the APCI
2.0 (which was disabled by default), I enabled "AMD Cool 'n' Quiet"
(which was also disabled by default).

Any obscure options that are on some sub-menu of a sub-menu
of a sub-menu? Something else I'm missing??

Thanks for any tips,

Carlos

I found this was a problem in earlier versions of Ubuntu when I was
running the Xen kernel. Are you running any kind of virtualization?

Not right now --- I was planning on installing VirtualBox (as I have
on
my notebook, where freq. scaling does work fine)... But I have not
installed it yet.

That's all I can say now. I also had a problem with an Asus M2N board a
year back which just wouldn't work right in either Windows or Ubuntu. I
promptly replaced it with another Asus board with the same chipset
maker, and it worked exactly as advertised. Who can tell with these things?

My phenom is fine with Hardy on an M3A, but I did need to put the
powernow_k8 module into the powersave configuration file in
/etc/power/

(I can't remember the filename (and I'm not near the machine!))
