Worked well, here, but has been some time since i did an install.

This one may be severly outdated, and corresponds to woody, not sarge.

Just go to a shell, and dd the /boot/vmlinuz-2.6.8-powerpc kernel to your prep
partition. I suppose that you where able to create such a prep partition with
partman, right ? And that partman didn't let you continue without creating the
prep partition ?

Ok, here is your problem.

Ok, can you give more details about this complaint ?

Not sure about this one.

We should have partman-prep version 3, and it should allow you to do the
install. Let me try doing an install here, and see what partman says.

I have not yet done the prep-installer .udeb, so this step is still manual.
dding the kernel to the prep partition should be enough.

Can't help here, launching it from the disk (boot disk) should work out of the
box, i think.

No problem, i am ccing the reply to debian-boot though, as this is the logical
place for this.

Please coordinate holger, he did some powerpc manual work.
