Thanks. After some further digging, I wonder whether Aravind's recent patch might help? The apu does have both PCI_DEVICE_ID_AMD_16H_M30H_NB_F3 and PCI_DEVICE_ID_AMD_16H_M30H_NB_F4 and lspci reports no driver for the F4 device.
Aravind would have to comment; my understanding is that the F4 device reports the power, not the temperature. You could try to apply the patch and see if it makes a difference. Worst case there will be no change ;-).
GR> Does the temperature increase with load ?
It seems to max out w/in a kelvin or two of the room's ambient temp.
Even under load ? Sounds weird. Question of course is if the chip really reports a useful temperature in the first place; this is something I can not answer, since I have neither a datasheet nor a system with that CPU.
