You probably can't.
The reason is that the initial messages ("pre-kernel") are
printed during text mode, while the kernel switches to
graphics mode (vt) soon. This clears the screen content
and replaces the system's text mode output by a graphical
output that "mimics" text mode.
However, you could try the following: In /boot/loader.conf,
set the following:
Now you can read the initial messages in text mode (!)
by pressing the Scroll Lock key and using the cursor
and page keys to move the buffer up to its top where
you can read the kernel and "pre-kernel" messages.
Keep in mind "startx" (and X in general) won't work with
sc anymore, it now _requires_ the use of vt!
See "man 4 vt" for details.
