racbern, I happen to know exactly what you are doing here.

DN2, this is post install, there are some application parameters and sizing questions that have to be answered after the first boot.

You can do exactly the same as on Sparc, the only difference is that you need to update the grub kernel boot like to add "-B console=ttya" to the kernel line, then you get the console on the text based ILOM and you can continue to answering the configuration questions.

The easiest way to get this working is to do the first run using autoexpect and then edit the generated script.
