looking in /etc/sysconfig/cpuspeed around MAX_SPEED= they suggest looking in
/sys/devices/system/cpu/cpu*/cpufreq/scaling_available_frequencies

i.e. for me
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_available_frequencies
returns all good settings for the cpu frequencies.
which _for_the_laptop_I_have_ is
1700000 1400000 1200000 1000000 800000 600000
Setting either MAX_SPEED=1000000 or MIN_SPEED=800000, and restarting the system, has had desired
effect for me, i.e., keep the laptop from locking due to overheat.

However, Nicolas suggestion of messing with UP_THRESHOLD might be better for you, or should be done
in addition to messing with MIN_SPEED=
