Now, does this mean that the chrp of does enable the mmu before booting,
and does program it in a way so that the translate (0) call will result
in 0x10000, or do i miss something ?

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.

Yeah, but in my case, i have no yaboot, and i know that these boxes are
also capable of booting from the OF.

But then, how comes the OF translate call is able to map the address 0
to the 0x10000 address ?
