Problems booting OpenSUSE on IBM system p machines

One of these days I was trying to boot the latest OpenSUSE image on one of my p series machines, to see how the new release was doing on power. However, I hit a problem: I was not able to boot the installation program on my openfirmware based machine. My friend Carlos figured out what the problem was, and he posted on his blog a solution for that problem. Thanks for your time and patience checking this out, pal 😉
