I think it isn't a cpufreq problem. I got the same behaviour without loading 
cpufreq module. Probably it is an ACPI issue.
It happens to me even in another case: if the computer boots in AC power but 
the battery charge is not full, when the battery lever reaches the top, the 
temperature goes up and the fan starts.

I have an Acer Aspire 1304 XC (Athlon XP 1800+)
