On my Dell laptop, a cpuspeed package is running. look in system-config-services, see if you have it on. I'm using a Nokia tablet now, don't have laptop here. Other thought I have is that cpuspeed, rather than throttling, is the only thing i use anymore. AFAICR, throttling would leave unused cycles, which is almost same as making the cpu slower.
