I own such a processor, and the modules I use are :
cpufreq_userspace
cpufreq_conservative
acpi-cpufreq
modprobe speedstep-centrino
If that dosn't work, I don't think you'll be able to scale your processor.

My favorite governor is the 'conservative' one. Under load, it will ramp up the frequency, but it will generally keep it as low as possible.
]]>what are the correct modules for Intel M Processors for powersave and cpusave?
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 13
model name : Intel(R) Celeron(R) M processor 1.50GHz
stepping : 8
cpu MHz : 1495.813
cache size : 1024 KB
# The powersaved startscript will load this module for CPU frequency
# scaling support. If nothing is specified here, the most common cpufreq
# modules will be tried. Entering the correct module will reduce the
# warnings in syslog during boot and probably speed up booting a bit.
CPUFREQD_MODULE=""
this is the module i need for my CPU...also im wondering which CPU govenor is the best or people recomend. I set it to ondemand as a start.
# If set to userspace, the powersave daemon itself will check
# for CPU load and adjust the frequency approriate.
# If set to kernel, the frequency will be adjusted by kernel
# CPU frequency governors. These are by default
# (kernel module - governor/powersave policy):
# ondemand/dynamic, powersave/powersave, performance/performance
CPUFREQ_CONTROL="ondemand"
