The lazy way:
Fetch Debian's "multi arch" CD, which contains 3 architectures: amd64,
i386 and powerpc:
http://cdimage.debian.org/cdimage/release/5.0.2/multi-arch/iso-cd/
The CD's bootloader stuffs are configured to select the best
architecture supported by your hardware (you can still manually force i386
in the advanced menu).
