Seems to be related to /usr/lib/pm-utils/sleep.d/80acpi-fan.
The script itself it works, but /proc/acpi/fan/*/state doesn't exist:

piggy:~ # ls -l /proc/acpi/
total 0
dr-xr-xr-x 3 root root 0 Mar 7 20:52 ac_adapter
dr-xr-xr-x 3 root root 0 Mar 7 20:52 battery
dr-xr-xr-x 3 root root 0 Mar 7 20:52 button
-r-------- 1 root root 0 Mar 7 20:52 event
-rw-r--r-- 1 root root 0 Mar 7 20:52 wakeup

and has been move to /sys:

/sys/devices/virtual/thermal/cooling_device*/cur_state

If I run:

for i in /sys/devices/virtual/thermal/cooling_device*/cur_state;
do
echo 0 > $i;
done

after the laptop has came back from suspend, it will stop the fans and
everything works as expected.

Maybe /usr/lib/pm-utils/sleep.d/80acpi-fan script should be modified to suppose
also /sys.
