You're right.
Strange though that BootX gives this kind of weird behaviour (2.2.15pre14
works fine for me).
I'll report about yaboot soon.

You "think" it worked right, but I'm pretty sure that if you do an
extensive memory testing, you'll discover that random bits of memory are
damaged and that the kernel is actually not fully reliable when booting
with BootX.

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.
