Note that BSD install creates a /boot/efi directory for the UEFI partition, with only two files (in subdirectories), whereas the SD card has /boot/MSDOS with a boatload of files, and different subdirectories, so I had to adjust the mount point in /etc/fstab for that.  My RPi is now (again) booting to the SSD (though I'll need to clone my customized kernel from git and (slowly) rebuild it).

  I'd have to look when I get home, but I wasn't thinking about any
EFI-boot the bsdinstall might have installed, just stomped on /boot/efi
with the equivalent from the SDcard image (uboot) and have stuck with
that ever since.  It's on my bucket list to play with EFI, but I haven't
seen (not that I've really looked) the parameters to overclocking and
such that I've current set in the uboot environment.
