Phoronix: Unified Linux CPU Boost Support Still Being Worked On
Kernel developers are still working on CPU Boost mode support for the Linux kernel's cpufreq to unify hardware and software-based solutions for CPU overclocking...
Interesting to see Samsung involved in CPU boosting since they're using it to cheat in benchmarks.
When it detects that a benchmark is running it overclocks the CPU.

They answer this question close to the beginning.
Short answer: yes, they are attempting to create a common interface for "all" cpu turbo/boost schemes.
I was under the impression at least for SB and IVB and Haskell, the Intel pstate driver in kernels 3.9+ handle the turbo frequencies.
