I have done some tests proving that it just can't be true. With Linux (2.2.15) I got a cpu temperature of 31 degrees celsius and with FreeBSD I got 47 degrees celcius, the tests where done on the same computer at idle state. Do I have to activate the HLT instruction on FreeBSD or something? The system I tested temperatures on was an Abit BP6 with dual celeron 500MHz cpu's. I tested the temperatures with a regular thermometer since I've never really trusted those built in sensors. ;) you need to add the following option in your kernel config file: options CPU_SUSP_HLT have a look at LINT, there are some other cpu related options like NO_F00F_HACK as well.
