I originally asked :-

A number of folk suggested using expect, which I tried but ran out of time 
before I got it fully working. However, I'm sure it would work.


Eric van de Meerakker then suggested the following "hack" with temporarily 
replacing /dev/tty with a plain text file, which seems to work just fine.
I had to put it in an rc script that runs when the machine reboots itself after 
install so that i'm working on the "real" filesystem. The script removes itself 
when it's done.

The following script performs the setting of the password when run as root:

--- cut here ---
#!/bin/sh
mv /dev/tty /dev/tty-device
mv /dev/tty-eeprom /dev/tty
eeprom security-mode=command 2>/dev/null
mv /dev/tty /dev/tty-eeprom
mv /dev/tty-device /dev/tty
--- cut here ---

Note the script I was sent doesn't actually set the password, because it's 
missed out the eeprom security-password= command :-)
