Please have a look at the two packages in :

  http://people.debian.org/~luther/gaudenz.

One is the :

  kernel-image-2.4.22-powerpc-small-pmac_2.4.22

package, which contain both the vmlinux and the .coff kernel, the other
is the :

  kernel-modules-2.4.22-powerpc-small_2.4.22

package whihc contain the modules built for the above kernel. Try them
out, and if you manage to boot them with miboot or something such, then
i will make a full build tomorrow again, and upload those, altough they
will be hold in NEW for some time.

Note : CCing to debian-boot and debian-powerpc, so someone with oldworld
hardware can give miboot booting with them a try and report back.

Friendly,
