No, you just fail to read the manual :)
please : man mkvmlinuz :)
mkvmlinuz allows to build the zImage.prep from the vmlinux outside of the
kernel build process, which is what we are doing, otherwise the zImage.prep
may indeed be the way to handle this.

Should work, i booted 2.6.14 on my powerstack II, didn't try 2.6.15 yet, but
will this WE.

Mmm, upstream may have broken prep on 2.6.15, i have to say i didn't test it,
will have a look this WE, ok ?

Mmm, i am leaving for two days now, but i will have a look afterward.
