OK, well your timing is impeccable. I just finished hacking up Eduard's
mini-iso.sh so everything is fresh in my mind.

This is good to know. I'll have to add it to the script. Is the type 
code tbxi? Because I think that's the critical thing, besides the 
folder blessing, that will let it load at boot.

ybin sets ofboot's type to tbxi, or if the boot menu is not being used, 
it sets yaboot's type itself to tbxi. So you might try that too. 
Probably it will confuse the machine if there are 2 files with that type
in the blessed folder.
