I think it's depends on exact BIOS.
At all my places where I can check - I could successfully boot from 
USB-FAT, USB-UFS, Cardreader-CF-UFS, Internal SD cardreader-UFS.
Currently I have Corsair voyager GT-16gb with installed PC-BSD, and it 
works well.
In theory making a bootable image is not difficult - install PC-BSD to 
totally free HDD (real or virtual) with size that we need, and then dd 
it to file.
Maybe before that cut some docs or else, to shrink a bit.
