AFAIK OSX does not overwrite yaboot, it just changes the
default boot-device.

Not a big problem with Openfirmware:

 * Hold 'Command-Option-o-f' after powering-up the machine
   (While you hear the sound..)

 * You should get a prompt

 * type 'boot hd:X,yaboot' , replace 'X' with your boot partition, eg:
   0> boot hd:2,yaboot

   (If you don't remember/know your boot partition, just try some numbers.
    You can't damage anything)
  .. this should load yaboot :-)


 After the system bootet, try to re-run 'ybin' to change the default 
 OR do it while you are inside the OpenFirmware prompt.
 # setenv boot-device hd:X,yaboot
 # nvstore (.. correct?)
 # reset-all


>   /dev/nvram: No such file or directory"
>   Warning: nvram will not be updated"

Hmm... strange..

Maybe a strace output would help
 # strace ybin 2>&1 | grep nvram

.. or 
 # ls -l /dev/nvram
