Thanks all, made _some_ progress. I installed rEFInd on my internal hard drive and now I can get to (and see!) the FreeBSD EFI loader. Unfortunately that's about as far as it gets. Once I tell the loader to boot it displays the EFI framebuffer information and then nothing else. This happens with 'kern.vty=vt' set and with or without 'hw.vga.textmode=1'.
