Headless Booting an Xserve...

I am setting up headless Xserve slave nodes (G5s). I have bootable disks that boot 'automatically through default settings': if there is a video card installed. But if there is  no video card I have to intervene with Open Firmware commands that direct the boot to hd:2,\yaboot.

I know that through an OF command the boot-device may be set- but that will not persit through an OF reset. Is there a way to set the boot-device in the ofboot.b file (or similar file) to make this change follow the boot disk?
