Console in text mode

What type of boot are you doing, UEFI or legacy ? UEFI doesn't have the text mode, not in the sense one is used to from BIOS (classic 80x25).
 
By default legacy boot (bios) stays in 80x25. Maybe graphical driver is messing this up. You could put hw.vga.textmode=1 in /boot/loader.conf.
