does arm64-rpi3 snapshot work?

[Nikolai Lifanov]

I tried booting my Raspberry Pi 3 with this snapshot:
https://people.freebsd.org/~andrew/arm64/rpi3-20160306.img.xz

I also tried to build one from this branch:
https://github.com/zxombie/freebsd/commits/arm64-rpi3

I tried updating to the latest firmware, but I still get a
rainbow screen every time.

Is there anything obvious that I'm missing?
