Yes, in theory the CPU would be forbidden to run at higher frequencies, so I'm not sure how viable 40MHz would be! I'm actually impressed you can go this low (limits are written in cpuinfo_min_freq and cpuinfo_max_freq in the same directory), my old cpu min is 400MHz. At this frequency stuff like firefox really start to struggle, I've never kept it that low for long. I normally scale down to about 1GHz without much visible performance impact except for compiling, and that is enough for fan to not kick in randomly everytime a web page has some somewhat heavy js or whatever it is I'm doing, but obviously you're looking at a different beast.
