[CPUFREQ] dual-core powernow-k8
With the release of the dual-core AMD Opterons last week,
it's high time that cpufreq supported them. The attached
patch applies cleanly to 2.6.12-rc3 and updates powernow-k8
to support the latest Athlon 64 and Opteron processors.
Update the driver to version 1.40.0 and provide support
for dual-core processors.
