Ummm... there isn't any way to do this from the OpenBOOT ROM....
But since it is SunOS 4.x, just interrupt the boot, and boot with
the -s paramter (b -s).
That will boot single user... then make sure / is mounted read/write...
if not, then mount -o remount,rw / should do the trick. Then depending
on if you want to use vi, etc you may need to fsck and mount /usr.
After fixing up the /etc/passwd file, sync and reboot.
