This patch updates the PowerMac cpufreq driver. It depends on the addition of the suspend() method (my previous patch) and on the new flag I defined to silence some warnings that are normal for us. It fixes various issues related to cpufreq on pmac, including some crashes on some models when sleeping the machine while in low speed, proper voltage control on some newer machines, and adds voltage control on 750FX based G3 laptops.
