Kernel modules are packaged separately and typically not included in the image 
by default; if you wish to include them you have two choices:

1) Install the kernel-module-<modulename> package(s) individually for the
module(s) you wish to use

2) Install the kernel-modules package to bring in all packages for modules you
enabled in the kernel configuration.

Not sure if you're aware how to install packages in the image, here's the
manual section just in case:
