Err, you souldn't have a ad4p2a if you are using gptboot.  gptboot expects you 
to create separate GPT partitions for each UFS filesystem and swap rather 
than putting a BSD label inside of a GPT partition.  EFI for amd64/i386 is 
not yet supported.  There is some work in a p4 branch to build a 32-bit EFI 
loader.
