After wrestling about two days with yaboot, the kernel boots fine.

Now I can recommend (on iBooks and alike):
- make yaboot's partition of type Apple_Bootstrap (anything else didn't work
for me)
- 1MB is fine (800k is minimum (still true?))
- splitting the swap partition is a good choice if you have a running system
- move it up/downwards to the second position (moving partitions is a nice
feature)
- if you want MacOS press option while booting
- "video=ofonly" is a good last resort help

Could someone please put the following explanations into the yaboot-faq:
  Option is the key with  alt and a half-fork on it.
  Command is the key with the apple and the knotlike figure
I had not been a Mac expert, so I had to guess.
