I was just able to install onto a Mac G4 Cube last week. I will let someone more experienced than me help more, but I will give a couple notes: 1) booting off USB thumb drive may be possible, but it is not officially supported. If you are able to boot the OpenBSD installer from a CD, then you shouldn't need to do this 2) I wasn't attempting to dual-boot, but my understanding of the install notes is that you want the first partition (i.e. the Mac partition) to be HFS+ and the second partition to be set up as "unused." I'm not sure why the installer would think you don't have a valid partition table, though... 3) “use Mac OS to move the bootloader to the first partition of the disk” -- this just means copying 'ofwboot' to the root folder of your mac partition
