I have RC3 running on a 1 GB RPi3B+:

FreeBSD 13.0-RC3 #0 releng/13.0-n244696-8f731a397ad: Fri Mar 19 05:54:12 UTC 2021
    [email protected]:/usr/obj/usr/src/arm64.aarch64/sys/GENERIC arm64
FreeBSD clang version 11.0.1 ([email protected]:llvm/llvm-project.git llvmorg-11.0.1-0-g43ff75f2c3fe)
VT(efifb): resolution 1824x984
module firmware already present!
real memory  = 993841152 (947 MB)
avail memory = 947474432 (903 MB)

It has the same version of start4.elf that you cited.   I haven't done
much testing on it though.
