Many AMD Family 10h (i.e. Athlon/Phenom II) chips have a faulty temperature sensor. It's safe to enable the driver here, but the kernel will detect affected CPUs and disable it automatically for them. In that case there's no reason to leave it enabled at all.
lm-sensors doesn't have an upstream config file for this chipset; the following is a best-effort attempt to write one:

Some of these can be disabled in the BIOS, in which case they won't appear here at all.
Known hardware issues
- The ethernet chip may forget its speed over a suspend and default to 100Mbit after resume. To work around this, put ethtool -s eth0 speed 1000 in the appropriate place in your suspend scripts.
- Most AMD family 10h CPUs have a processor erratum related to the temperature sensor's unreliability, which is why the driver is disabled above.
- The SB700 chipset is affected by a kernel quirk that prevents it using message-signalled interrupts due to the possibility of data corruption when a floppy drive is used. There's a patch on the Gentoo forums (updated version here) to disable the kernel's workarounds, which may or may not improve performance slightly.
