Probably compiler updates or something? I really wouldn't worry about it 
too much. I'd worry more about loader, since we know boot1 could use the 
console but loader doesn't show up.

How did you set it up in the first place? If you have a FreeBSD-only 
system partition (like the installer sets up), you just dd 
/boot/boot1.efifat to the EFI partition. Otherwise, it's FAT and you 
copy /boot/boot1.efi to somewhere your boot manager can find it.

The EFI boot block finds the first UFS partition -- on any disk -- and 
tries to boot from it. If you have multiple FreeBSD disks connected, 
that will very likely result in madness.
