It has been broken by the following patch:

commit 977b6b91cee1132f8c7b12d22f4b273091598e44
Author: Amit Shah <amit.shah@redhat.com>
Date:   Thu Feb 25 19:26:11 2010 +0530

    ppc440_bamboo: Add 0.12 and 0.13 machine types for backward compat

    Add a 0.12 machine type for compatibility with older versions. Mark the
    default one as 0.13.

This patch change the default PPC machine to bamboo, while it was 
previously g3beige. I haven't noticed the problem, as my test script
sets the machine with the -M argument.

I have just pushed a patch to HEAD to fix the problem.

BTW, as in the s390 case, does this patch make sense for powerpc? If no
one uses such a thing, those two patches should be reverted..

Given that the bamboo board is present since version 0.10.0, I think it
make sense.
