Yep, that seems coherent with what Ben told me. But since we will make
the kernel smaller anyway, in order to fit on a miboot floppy, it should
not be a problem.

Nope, only miboot and chrp/prep/chrp-rs6k support compressed kernels.

That would be good if it was fixed, or at least properly documented.
