Since this is a daemon, it should be started at boot via /etc/rc.d/rc.local: /usr/bin/thermald It might be necessary to create /var/run/thermald/ first (depending on your local system setup) Also it would need to be stopped before shutdown, so an entry could be added to /etc/rc.d/rc.local_shutdown as well: killall thermald CONFIG_X86_MSR is listed as an (optional) dependency, msr-tools can be installed from http://01.org/msr-tools via src2pkg (www.src2pkg.net/) If you installed a previous version of thermald, you may need to uninstall it and then install this one instead of using upgradepkg
