Remember trying OpenBSD on an iBook G3 and it preferred a MBR table? I was thinking of dumping my OS X partition and replace it with a lightweight OpenBSD install.
EDIT: Works as it should following the dual boot guides for OpenBSD and MorphOS, no boot icon for OpenBSD though (just set it to auto-boot) and there aren't even any PowerPC packages yet for 6.7!
