This is so you can use the 32-bit libraries in the 64-bit system. It is
unnecessary if you do all your 32-bit stuff in the chroot.

This looks right to me; it is what I have done.

I wouldn't mount /etc to the chroot, and /dev hasn't ever been
necessary. Someone else needs to help out here...
In that HOWTO, _I_ would skip 1.3, 1.4, and 1.5. The only changes I
make to the real system is to /etc/fstab.
