This is a collection of 2 bugs, which I think are related (hence why I am
reporting them both here) as they both happen as a result of hibernate/restore:

1. After a hibernate/restore cycle, the fan management option (the value of
pwm1_enable) is not restored; and also 

2. After a hibernate/restore cycle, when automatic fan management is applied
("echo 2 > .../pwm1_enable"), this doesn't work - the nouveau driver takes the
fan speed to 2 and keeps it there *regardless* of the temperature of the video
card, which may cause the card to BURN OUT!

The kernel in use is 3.9.6 with the stock-supplied nvidia driver. For more
