running an armel image on 12.04

Hi,

I'm trying to run an old armel image on 12.04 on Snowball. It doesn't run because there's no armel support; starting with a missing /lib/ld-linux.so.3

How can I add armel support? I tried this:

# dpkg --add-architecture armel dpkg: error: unknown option --add-architecture

# apt-get update ; apt-get install dpkg [...] dpkg is already the newest version.

# dpkg-query --show dpkg dpkg 1.16.1.2ubuntu7

Thanks for any pointers you can give me.
