You shouldn't need this patch, especially if you jump to a recent version of
yaboot such as 1.1.1 or the like.

Looks like yaboot is working just fine.

Do you have any numbers on the lcd display on the front of the B50?

This looks almost like something isn't right with the kernel. I assume that
you're using the same vmlinux for your default kernel in your yaboot.conf that
you are dd'ing when you tried that.

If you copy the kernel directly, you should set the OF variable boot-file to at
least root=/dev/sda3
