cpufreq-bench test on X86 platforms

I am trying to investigate ondemand governor's limitation in Linux kernel. As part of that, I have found a tool called cpufreq-bench which can be used to determine the performance degradation due to ondemand governor compared to performance governor.
I have used this tool on OMAP platforms and able to see the issue. Now I would like to demonstrate this issue on x86 platform to conclude that it's a generic governor problem and nothing specific to ARM based SOCs.
I would need some of your help to run this test bench on some of recent X86 platforms that have support for many P states. (My PC is little old which has only 2 p-states (2.8GHz & 3.4 GHz), so performance degradation is not much visible).
More details on the tool and test procedure can be found at
Pls ping me if you need any assistance in testing.
Looking forward for your test results.
