The G revision chips don't provide correct readings for some reason.
It's interesting to note that only the last two K8 revisions, F and G,
are documented by AMD to have temperature sensors, however, most G
chips appear to report invalid data, whilst F chips and most
undocumented pre-F chips are working just fine.
