No.  CHRP and PReP share the same partition type to boot from, but
they boot different things.  CHRP machines boot ELF executables (like
yaboot or CHRP vmlinux images).  PReP machines boot PReP boot images.

So, you will write the yaboot executable (stamped with the correct
note section) to the PReP boot partition on a CHRP machine.
