installing OpenSUSE in jail chroot

how can I install OpenSuse 11.2-x86 on a chroot directory (a jail) in OpenSuse 11.2-amd64 ?

I have searched with google, but all documentation is for ubuntu.

I want to install some apps that are only for 32 bits and I dont want a mess in my system.

Sorry for my english, i hope someone can guide me.
