It seems like the /sys/class/drm/card0/device/hwmon/hwmon0/pwm1 value for my
GeForce 9600 GT (10de:0622) will never go above 80.

If I do echo 1 > pwm1_enable (to set it to manual control), then try echoing
values to pwm1, it basically acts as if any value above 80 is identical to 80.

[root@adam hwmon0]# pwd
/sys/class/drm/card0/device/hwmon/hwmon0
[root@adam hwmon0]# echo 79 > pwm1
[root@adam hwmon0]# cat pwm1
79
[root@adam hwmon0]# echo 81 > pwm1
[root@adam hwmon0]# cat pwm1
80
[root@adam hwmon0]# echo 100 > pwm1
[root@adam hwmon0]# cat pwm1
80
[root@adam hwmon0]# echo 100000 > pwm1
[root@adam hwmon0]# cat pwm1
80
[root@adam hwmon0]# echo 30 > pwm1
[root@adam hwmon0]# cat pwm1
30
[root@adam hwmon0]# echo 100000 > pwm1
[root@adam hwmon0]# cat pwm1
80
