[HOWTO] Installing OpenWrt on Cyberoam CR15(w)iNG and CR25(w)iNG

@konus

I don't know if this is any help, but on my PC i'm using pwmconfig to control the fanspeed.
I know on OpenWRT there's a package called Kmod-hwmon-pwmfan,
perhaps this might do something similar.
Please refer to CPU FAN Control (x86_64)
