The OpenBSD site says that it is safer to install OpenBSD/i386 instead of OpenBSD/amd64 on Intel chips with AMD64 extensions that don't support the PAE NX bit. Does the same apply with FreeBSD/i386 and FreeBSD/amd64, or is it handled differently in FreeBSD? If it does apply, how can you find out if your chip supports the PAE NX bit? Is there a feature that will show for the cpu in dmesg?
