I wanted to install and try OpenBSD on my Librebooted Thinkpad T60, but unfortunately it is not possible to use full disk encryption with a non-custom Libreboot rom (you apparently need SeaBios instead of Grub2 for this to work). I find it quite sad, because I think Libreboot + OpenBSD would be the ultimate security and privacy-focused combo.
