I think the kernel should disable SHE by default on the 701 models. I don't mind if it provides a "force_cpufv" option with an appropriate warning. The 701 models aren't shipped with any way to control the SHE. It is a form of overclocking which is not supported by the vendor. On the other models, SHE is a marketed feature which users will expect to work reliably. We should treat these cases differently in the kernel. I don't think it should be left to userspace to get this right. There are other distributions than debian :-). I've seen at least one desktop applet which controls SHE. I expect it has a similar option to toggle SHE automatically when switching between mains and battery power. If we change the kernel, it will affect everyone. The ABI doc for eeepc-laptop doesn't say "writing to cpufv may break", so we need _some_ change to the kernel sources :). I think it's better to "fix" this in the code and not just add disclaimers in the documentation.
