Although I haven't been following Mac OS X much, I'm almost positive that
if you install using UFS you need an HFS(+?) boot partition for it too.

This is slightly wrong.
"hd:x,\\yaboot.tbxi" would run the program "yaboot.tbxi" from the
(blessed) System Folder.
"hd:x,yaboot.tbxi" would run yaboot.tbxi from the root level of partition
x.
Little known fact: if you omit the "x", OF will boot from the first
non-driver partition, usually your Mac OS system. This is convenient when
you can't remember partition numbers.
