fancontrol with IT8705F

Hi Jean,

thanks for your reply. I rewrote fancontrol now and it works ok. But I'd still 
be interested in a better solution. I'll contact the author of speedfan to 
see if he really got it to work better or just mapped the 0-10 values to his 
0-100% settings (if there are just 10 different speeds I can set my fan to I 
can live very well with the fancontrol hack. However if it is possible to set 
it to more values it would be nice because right now it goes from 1500 RPM 
directly to 2000 and then to 2200 and doesn't change much more after that)

Output of the isadump:

I'll write more when I have a reply from the speedfan author.

Thanks again,
