reading the specs, it seems to me that the a4-4000 processor (amd fam
15h model 13h) has the tdp running average feature, implemented in
the fam15h_power module:
D18F5xE0, page 456, BKDG for AMD Family 15h Models 10h-1Fh Processors
http://support.amd.com/TechDocs/42300_15h_Mod_10h-1Fh_BKDG.pdf
if this assumption is correct, the module fails to probe the device
only because the pci id to query is different, so the attached patch
should fix the detection
it is untested as i'm not familiar with the hardware and i really
appreciate some suggestion from an expert here
c-ya!
