On IBM CHRP hardware, OF executes in real mode (ie, relocate off).  It
then branches to yaboot/kernel still in real mode.  It's not until a
fair ways into the kernel boot that we turn relocate on (after we're
done making calls to OF).  This also means that Yaboot executes in
real mode as well on IBM CHRP machines.
