The patch looks fine to me, although I have a few small comments, see
what I write below.  This evening I am going to test the patch to see
if it works for me.

There was a discussion about this before, please read it for details I
might have forgotten.  But ATM the PC version works for the PPC as
well.  There is no platform specific code there yet and I want to keep
things shared as long as it is possible.  Doesn't it work for you or
are there any issues?  The biosdisk code is the code, together with
the i386 specific code, I am the least familiar with.

Two spaces are required here, please fix this in the other places in
the changelog entry/comments as well.

Can you give the enums a prefix?  For example
`GRUB_IEEE1275_NO_PARTITION_0' can be changed to

>       * kern/powerpc/ieee1275/init.c: Don't include grub/machine/init.h.

Huh?  What is this whitespace change?  And there is no need to mention
it in the changelog in case it is required.
