Each kernel module has postinstall script (added by kernel.bbclass) 
which calls 'depmod -a' and update-modules. Opkg intercepts depmod calls 
to make it just one call in 'opkg configure' during first boot. In 
effect your rootfs has all module dependencies generated on build time. 
You can probably remove second part of those postinstalls to not call 
them on device at all.
