pwmconfig was being run with sudo.
echo to pwm1_enable and pwm2_enable results in:
bash: /sys/class/hwmon/hwmon0/device/pwm1_enable: Permission denied
pwm1_enable is set at 2, pwm2_enable 1
I guess this means its a driver issue? Sensors detect identifies:
Driver `w83627ehf' (should be inserted):
Detects correctly:
* ISA bus, address 0x290
Chip `Winbond W83627DHG Super IO Sensors' (confidence: 9)
