[ltp] Fan noise fix

[Charles Gillet]

I'm using the cpuspeed utility that comes with FC2, which I guess is 
very similar to cpudyn?  I edited its config file to make sure it knew 
the location in /proc for AC power status and temperature.  I picked 60C 
for the ceiling (point at which CPU is slammed to slowest MHz) since the 
hottest I could ever get the system was 63C during my testing.

56C seems really hot for idle.  Is there a port for nitrous oxide on the 
side that I don't know about?  :-)

cat /etc/cpuspeed.conf
VMAJOR=1
VMINOR=1
OPTS="-t /proc/acpi/thermal_zone/THM0/temperature 60 -a 
/proc/acpi/ac_adapter/AC/state"
