Correction, most of what I said was wrong in detail, but the basic
message is still correct :-)

1) In F9 coretemp now comes with the kernel (in FC8 I remember
downloading and installing it separately).

2) The package you need is lm_sensors.

3) You need to run sensors-detect (as root) to set it up. This isn't
automatic because the config script is interactive (some of the probes
can potentially crash your system).

Sorry about the confusion.
