That's what I would neither call pre-boot nor post-boot, but during-boot ;-)

Similar solution: You have to tell the boot loader to use serial console.
Out of memory I don't know which stage asks for GELI... If
/boot/loader.conf (3rd stage) is too late (which I don't think, so it's
worth trying boot_multicons="YES" in /boot/loader.conf), you can pass
"-nDS115200" to the 2nd boot stage, by putting it into /boot.config.

Hope that helps,
