Load ko

Compiling Kernel Modules for Raspberry Pi

Copy your .ko module to /lib/modules/3.2.27+
Edit /etc/modules and append your module to the end of the list.
Mine looks like:
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
# Parameters can be specified after the module name.

snd-bcm2835
spi-bcm2708
i2c-bcm2708
i2c-dev
rpi-pwm

Next, run: depmod -a
Next, run: modprobe <yourmodulename>
