I had not noticed it was not loaded. This maybe a bigger problem. With
the latest FC6 kernel this module gets loaded and thus suspend fails. I
rebuilt the same kernel but plopped this patch in. The module does not
want to load:

# /sbin/modprobe acpi-cpufreq
FATAL: Error inserting acpi_cpufreq
(/lib/modules/2.6.18-1.2708.cpufreq/kernel/arch/i386/kernel/cpu/cpufreq/acpi-cpufreq.ko): No such device

This is why suspend works. But now this module won't load.
