It does seem a bit late for wheezy. And at least yaboot now seems to
be a version that might actually work. I seem to recall some issues
with ofpathname, but I can't quite remember what they were right now or
whether they were fixed or not. A quick check says that yes indeed in
wheezy the ofpathname issue (bug 607001) was fixed.
Actually given grub is 1.99 in wheezy I think it is safe to say it
won't work in a number of cases. 2.00 fixed some endianess issues with
software raid among other things that matter to powerpc, which is why
I am running grub 2.00 and not 1.99 now. The older versions were OK
with the old mdraid format, but not the 1.x format which is of course
now the default in debian's installer.
