patch

obsolete

>This patch changes pwmconfig to perform much smaller steps when testing fans
>which have by far most of their speed change with PWM values below 16. This is
>true for the fan shipped with an AMD Athlon64 3200+ CPU.
>
>To make the fan control for this fan work, it is also necessary to adjust the 
>MINSTART value in /etc/fancontrol considerably down, probably to somewhere
>around 5 (4 works at least while the fan is new), and to adjust the MAXTEMP
>value upwards to way above what one consider reasonable (try 90). The latter is
>necessary as long as the fancontrol scripts interpolates along a straight line
>to find a PWM value as a function of CPU temperature.
