Yes, same as for ACPI performance states and throttling, that's what the 
klaptop_acpi_helper is for. This is installed with setuid root for these 
purposes. This was introduced by Paul Campbell when he added the ACPI support 
some time ago, I just reused it for CPUFreq.

I will have a look at cpufreqd as well as acpid. At least it would be a good 
idea to make klaptopdaemon aware of these tools to prevent this situation.
