The module name is cpufreq_<governor_name>. In particular, when I was
compiling the ondemand governor as a module it was

These are the kernel options i have enabled:
Power management options --->
CPU Frequency scaling --->
[*] CPU Frequency scaling
<*> 'ondemand' cpufreq governor
<*> AMD Opteron/Athlon64 PowerNow!
[*] ACPI Processor P-States driver
I would also suggest checking out the gentoo-wiki entry on PowerNow. [1]
