Kernel modules are packaged using ipkg just like anything else.  Look
in tmp/deploy/.../ipk/... and should see a bunch of
kernel-module...ipk files.  To add them to your image, you need to add
a run-time dependency somewhere (RDEPEND).  This can be about
anywhere, but one place is your local.conf file?

DISTRO_EXTRA_RDEPENDS += "\
        kernel-module-mmc-block \
        kernel-module-mmc-core \
        kernel-module-pxamci \
        kernel-module-ac97-bus \
        kernel-module-ucb1400-ts \
        kernel-module-evdev"
