Modern FreeBSD versions use newer vt(4) console driver that defaults to pixel mode rendering
and depends on correctness of ACPI tables of motherboard's firmware much more
than old syscons(4) console driver that is still available.
You should try escaping to the loader prompt first and run these commands:

set kern.vty=sc
boot

Try it and see if it helps. If so, don't forget adding "kern.vty=sc" to /boot/loader.conf
after installation.
