In fact the northbridges are quite different, only the temperature 
reporting part has been kept the same. So for the purpose of this driver 
(and only in this case) we can handle the northbridges as if they were 
compatible. But in fact the PCI-IDs changed, so we have to list them 
(and add them if new CPUs are released). But yes, Llano and Brazos 
(Fam12h and Fam14h) share the same northbridge, hence the same PCI-ID.

Andre.

That is true. I await more of this confusion when Fam 15h (aka 
Bulldozer) hits the market, since people may mix it up with family 15 
(0Fh) aka K8 ;-)

Andre.
