I WAS cross-compiling, but the problem persists when compiling 
natively. I don't net-boot but load the image from a HFS+ partition. I 
can't boot

http://membres.lycos.fr/schaffner/vmlinux.orig

which is a compilation of linux-2.6.4 with

http://membres.lycos.fr/schaffner/.config

I can, however, boot

http://membres.lycos.fr/schaffner/vmlinux.patched

which is the same after the following patch:

http://membres.lycos.fr/schaffner/boot-of-works.patch

Maybe the problem is specific to the model of the machine?

Thanks,

Martin
