This is not something that is currently supported, as it relies upon a specific way of setting up the memory. Memory setup is very different on BSD vs Linux - Linux targets use the hugetlbfs filesystem, while BSD ones rely on a separate kernel module to reserve large blocks of memory from the kernel at boot time.
