how to set persistent cpu frequency

I'm using the imx6 SoloX eval board. During boot, I'm drawing too much current through my ARM Core 1.35V supply.  I see that I can throttle the Core power by limiting the operating frequency, but no matter what I set the cpufreq governor to, it always seems to use "on demand" during boot-up. What I think I need is to have the governor set to powersave during bootup, which will set the core to the lowest available frequency, then I can just change it to on demand later, but how to I make the device use a particular governor during boot?  My hope is that I don't have to mess with a custom kernel build, but I do know there is a "default" option in the kernel menuconfig.  Is there a way to do it via startup script or some persistent setting change?
