Modules can be divided to three part:

1) need to boot (placed to loader.conf)
2) need to work (placed kld_list)
3) need to distribute (placed in /boot/kernel)

On install disk (and for first boot) all modules must be in
loader.conf. After boot to installed system we can edit loader.conf
and kld_list. Manualy or by tools, but after boot.
