Don't know if this can help you. For me speedsteps are working fine with the same SSDT installed in Mavericks, but I've migrated to clover. If you are interested in Facetime and iMessage this is a necessary step and maybe solve your problem regarding the speedsteps
Thanks! I was already thinking about "updating" to Clover so this is pushing me a bit more in that direction
