What makes you think, that S4OS is supported in FreeBSD?
AFAIK only S4BIOS is working at the moment.

Regarding S3, here is what I had to do to make it work on my ThinkPad R51
running 5.4-STABLE:

In /boot/loader.conf I added: 
acpi_video_load="YES"

In /etc/sysctl.conf:
hw.acpi.reset_video=0
hw.syscons.sc_no_suspend_vtswitch=1

Maybe these settings work for your system as well.
