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

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

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