PMBR is a simple variant of MBR which does know enough to parse GPT
partition table and how to load bootcode from the "freebsd-boot"
partition. Then gptboot does search bootable UFS partition.
At this time we do not have any  bootcodes like booteasy for GPT.
But you can try to use bootme and bootonce GPT attributes (see
gpart(8)). Also you can use grub boot loader.
