  The "hd:" without a partition number signifies the default bootable 
partition on the drive. The value can be seen at the OFW prompt with

0 > printenv boot-volume

  .. and the contents found with:

0 > dir hd:

  Also, try:

0 > printenv boot-device

  On my Powerbook, this is "hd:,\\:tbxi", which means to go to the 
default directory ('\\') on the default partition, and load the file of 
type 'tbxi'.

  I haven't mucked around too much with this, but I suspect you need a
Forth script similar to src/release/powerpc/boot.tbxi which would
live on the default boot partition. Then, you could setenv the
'boot-command' variable in OpenFirmware to boot with this file.
