For linux I used "boot hd:2,yaboot" as described in the yaboot HOWTO.
For Mac OS X I booted off the Mac OS X install CD and ran the startup
disk utility to pick the Mac OS X partition to boot.

sorry it was there but its default permissions kept it from being shown.
I fixed this and its now at:

unfortunately, my nightly yum update caused a new kernel to be loaded
and the file currently there has a new kernel added so its not exactly
the same. however the basic information such as partition=4 and
macosx=/dev/sda3 looks the same. I'm not at the machine right now to
actually try and reboot again, at least not if I want to be sure the
machine stays up. :)

The /proc/modules info is here
The /sys info is here, but there were many errors in doing the rsync copy:

Thanks for taking a look,
