Well, it will work because I've done it before. :)
Just put "brokenosx" in your yaboot.conf file (apparently it doesn't really 
matter where) and run ybin again. I don't know why the author of yaboot calls 
it "broken" because apparently it's required (from what I've heard) to boot 
OS X on an HFS+ partition. In my experience, running OS X on UFS is by far 
the more broken of the two options. Many apps simply won't run. But whatever.

This option tells yaboot to ignore the normal System folder blessing rules and 
just load OS X directly when you select the x option in the boot menu. That 
way, the OS 9 System folder can remain blessed (and selecting m in the boot 
menu boots it), but you can still boot OS X too. So I think then, to get this 
working, you need to select the OS 9 System folder in the Startup Disk 
control panel. I don't know about the "system hanging after it loads BootX," 
it certainly never did on my TiBook I 500. I'd suggest giving this a try, it 
worked for me.
