For those who asked why no application had made use of smart reflex, take a look at cpufrequi, it also has options for ignore nice load and using different govenors.
I haven't looked into using any of these for a while so can't remember what was stable and what was not, also i dont think changes made with cpufrequi persist after reboot (not 100% sure though) so imo its a safer way of testing these things
