I've yet to figure out what the FreeBSD equivalent to cmdline.txt
is. That might be the key to making your approach work.

 
Fbsd 13.x on a pi4, booting off a usb disk:
 
# cat /boot/msdos//config.txt
[all]
arm_64bit=1
dtparam=audio=on,i2c_arm=on,spi=on
dtoverlay=mmc
dtoverlay=disable-bt
device_tree_address=0x4000
kernel=u-boot.bin
 
[pi4]
hdmi_safe=1
armstub=armstub8-gic.bin
 
 
At least, I assume that's the equivalent file. :-)

 
AIUI, config.txt sets up the Pi, cmdline.txt furnishes
runtime arguments to the kernel when that kernel is
linux. If this isn't true somebody please correct me!

Does it show the FreeBSD beastie text-mode screen?

In which case you can probably set things up in loader.conf:
https://docs.freebsd.org/en/books/handbook/boot/index.html#boot-loader

the same way you do on x86.
