2111	No fan control on Tyan s2865/S2864	muranyia@…	ruik	"Sensors are detected and working, pwmconfig run (with some help), but fancontrol gives error and does not work on my Sun Ultra 20 Workstation. Main board is Tyan Tomcat K8e, S2865 (this Sun version is called S2864). Its told this board has a DME1737 chip.
OS is FC5, kernel 2.17, with NVidia kernel module.

pwmconfig is able to control the fans (the one PWM-capable I have), however it gives the same Access Denied messages meanwhile that fancontrol does.

Thanks In Advance!
