Afaik it is more efficient to run a notebook with max cpufreq for a short time than to run it with a lower cpufreq for a long time. You should not forget, that the CPU is only one component that uses energy and afaik compared to everything else, it is not so much. When it is clear, that the CPU is the bottleneck for suspend, then running the CPU with max frequency should save some battery life. But imho it is better to test it first, maybe the ondemand govenor is even better.
