Not working. You can modify the above procedure (installation w/o encryption) to install OpenBSD using full disk encryption, and it appears to work, except that its not yet clear how to actually <i>boot</i> an OpenBSD+FDE installation using libreboot+Grub2. If you get it working, please let us know.
+ If booting in text mode (framebuffer mode might also work), it
+ might be possible to chainload the OpenBSD or LibertyBSD bootloader
+ from the MBR section on the internal storage device. This way,
+ it would be possible to boot with an encrypted OpenBSD or
+ LibertyBSD installation. Please let us know (contact details
+ are on the libreboot homepage) if you get it working this way.
+ Alternatively, it would be good to port OpenBSD either natively
+ as a coreboot payload, or port it to libpayload (payload library
+ in coreboot; it has a basic C library and a few functions for
+ certain operations e.g. text/bitmap). <strong>This would be ideal,
+ because then it would be possible to boot a truly fully encrypted
+ OpenBSD or LibertyBSD installation, by putting everything in
+ the flash chip.</strong>
+ Alternatively, modifying GRUB to support booting fully encrypted
+ OpenBSD installations would be possible, but probably not feasible;
+ it's an alien codebase to the OpenBSD project, not tightly integrated
+ and the OpenBSD bootloader already works.
