There's a few things you can try. Both drivers put the various values & speeds in sysfs, tho in different places. You can do a test such as overnight idle or something like that and compare the averages. Also, does the new driver properly react to load ? The algorithm should be identical and the factors fed to it as well, but there's always the possibility that I screwed up something.
