The module was not working on your laptop even when suspend was failing.
That is what the absence of /sys.../cpufreq says. If this module was
working for you earlier and stopped working recently or even otherwise
both this and speedstep-centrino does not work on your platform, that is
a separate issue. Was this module working and cpufreq supported on your
system with any earlier kernels?
