This was done by Juerg. The driver can be downloaded from the lm-sensors.org website in devices section. It seems some version of fam6 model D does not have any temperature register in > 0xc0000002: eax=0x00000000 ebx=0x08000810 ecx=0x08100f13 edx=0x42040000 Jason, Please can you look to some more recent version of C7 data book, where the values for temperature are stored? (normally they are for cpuid EAX = 0xc0000002 in EAX. Here are zeros. I dont know what CPU revision it is exactly. I guess we will need to read some other MSR to get current version. Juerg do you know this? Its should be MSR 1154h. All I know that the cpu is also at HP Mini-note 2133.
