The various kernel modules can either be compiled into the kernel or
loaded dynamically. There may be one or two exceptions that only work
compiled in and some devices are obviously needed to boot the system.
The modules that aren't compiled into the kernel will be available as
loadable modules. An option compiled into the kernel is permanently
available, consuming ram etc. A loadable module can be unloaded if not
in use.

The main reason for configuring and building your own kernel has been to
remove things you don't want, therefore reducing minimum ram usage
- less important for current systems with plenty of ram.

You can configure the crypto module to be automatically loaded during
startup by adding crypto_load="YES" to /boot/loader.conf
