Hi Juerg,

In short - it works! Relevant outputs are below. Just a few questions -
would you recommend to use this code in production system (as for me looked
like simplified version of previous driver, looks like clean and nice, but
is it stable enough)? Perhaps stupid question but is there any kind of
'WHQL' for linux kernel development?
 
Syslog output:

Feb  5 14:04:36 farm dme1737 0-002e: Found a SCH5027 chip at 0x2e (rev
0x69).
Feb  5 14:04:36 farm dme1737 0-002e: Optional features: pwm3=yes, pwm5=no,
pwm6=no, fan3=yes, fan4=yes, fan5=yes, fan6=yes.

Sensors output:

temp3:       +36.2 C  (low  = -127.0 C, high = +127.0 C)
cpu0_vid:   +0.000 V

(fan1 - CPU, fan5 - chassis, temp1 - temperature margin in case of CPU
supporting 'PECI' feature (negative value is ok), or CPU temperature
(usually positive number), temp2 - motherboard, temp3 - dimm).
