FreeBSD uses a.out because there aren't any good reasons to change.
I'm not sure why Linux ended up with so many problems in their a.out
format, and won't speculate to avoid starting a flame war. ;^)
ELF does not grant any larger address space than a.out, the address
space is pretty much dictated by the adressing model of the MMU. As far
as I know, both Linux and FreeBSD use the i386 32-bit flat memory model,
which yeilds a virtual address space of 2^32 bytes.
FreeBSD does support Linux ELF binaries if you load the Linux emulator.
