K8V-MX uses AMI BIOS, right?
Some Linux kernels failes to activate ACPI for AMI BIOS and, then,
powernow-k8 reports 'no PSB ...". Please check syslog whether ACPI is
working well.

This happens also on my 939S56-M (Asrock, AMI bios) and Athlon64 3200+
(Winchester core), Fedora Core 5, and ASUS A8N-VM CSM (see
<http://www.nvnews.net/vbulletin/showthread.php?t=63378>) etc.

Hope this helps, Hideki.
