Well, I see that this thread has resumed after three months of being idle. Is there a chance that either Cristiano's or Tom's version can be included? By the way, I currently run my eeepc 900 with cpufreq disabled. Looking at the patch, with Tom's mods to eeepc_laptop I could do the same, am I right? I see only an include for cpufreq.h and nothing else.
