We use 64 bit OpenSuSE kernel 2.6.27 (patched for right numactl work) 
w/OpenSuSE sensors 3.0.3 (w/libsensors4) packages installed.

Motherboard Supermicro X8DTI has w83795adg (I beleive) chip, and I 
obtained from Supermicro Tech Support the necessary data (see below) 
for /etc/sensors3.conf

1) 1st of all, I need to install "stand-alone" w83795 driver for my 
kernel.    
Do I understand correctly that simple issuing of "make all" under root 
is enough ?
(of course, I do not say about w83795 loading).

2) Am I right in a pair of "compute" statements for in3 and in4 
values:

compute in3 @*0.032, @/0.032
compute in4 @*0.008*6.62, @/0.008/6.62

if I base on data supplied by Supermicro (below, they are for 5V and 
12V) ?
