For Nocona I would suggest using the in kernel ondemand governor. More
details here
http://www.intel.com/cd/ids/developer/asmo-na/eng/dc/xeon/reference/1959
10.htm

And newer versions of the userspace governors should be able to handle
SMP processsors. Earlier versions didn't. Not sure which version of
cpufreqd you are using.

Thanks,
