The armel repositories are now available from the normal Debian mirrors.:
Here is a section of the Wiki Page which explains this:
The armel port is now available from the normal Debian mirrors (you can see the full list at Debian Mirrors).
An example using a mirror in Germany:
deb http://ftp.de.debian.org/debian unstable main
# old sources
probably no longer available...
add this line if you want latest packages from oesf :
deb http://matrixmen.free.fr/zaurus/debian sid main contrib non-free
This is now up to date. Thanks to the Wiki page contributor and to the post from dkm which persuaded me to update this post.
