I was not sure of the meaning, but it is clear now, thanks.

Bah, i am not familiar enough with the PReP boot procedure to reply
here. It is possible to embedd those boot infos into the kernel, but
this happens at build time, and i am not aware of it being possible to
do it later, but let me investigate.
Could you perhaps copy the kernel to a prep partition, and boot it from
there ?

Well, the above should be installable in parallel, but maybe the prep
box won't like it, i understand you. Let's see if we can manage
something with the serial cable.
