Temp monitoring on alix boards

[matrix200]

I know this is an old thread : http://forum.pfsense.org/index.php/topic,12296.0.html , but it would be nice to monitor cpu temps on this platform.
I sometimes worry during the summer as the device appears pretty hot to touch.
I tried several hardware monitoring packages mentioned here on the forum and none seem to support lm86.
I was able to get the voltages but the temperature shows  128C which is obviously wrong.
