Actually it is kinda expected.  Please see CAVEATS section of the new 
manual page:

For Family 10h and later processors, ``(the reported temperature) is a 
non-physical temperature measured on an arbitrary scale and it does 
not represent an actual physical temperature like die or case 
temperature. Instead, it specifies the processor temperature relative 
to the point at which the system must supply the maximum cooling for 
the processor's specified maximum case temperature and maximum 
thermal power dissipation'' according to BIOS and Kernel Developer's 
Guide (BKDG) for AMD Processors, 
http://developer.amd.com/documentation/guides/Pages/default.aspx.

BTW, the temperature reading goes up when the system is loaded and 
goes down when it is idle, right?  Just making sure...

Thanks,
