Don't forget about mail and sound and probably a lot more. The chroot
way will allways be a case-by-case option though. Every user can easily
create one for their needs but covering all the possible configurations
so it works out-of-the-box for everyone will be hellishly complicated.

Me I just use ia32-apt-get + dpkg-cross and do

  apt-get install <32bit only programm>
  apt-get build-dep bla-armel-cross
