Hmm, can you enable all the debug statements in the driver? Simply edit drivers/cpufreq/powernow-k8.c by adding #define DEBUG as the very first line in the .c file. Then rebuild kernel, reinstall and reboot with "ignore_loglevel log_buf_len=10M" on the kernel command line. You can send me dmesg privately if you prefer.
