Thanks, Myles. This wiki maybe need update, :) I supposed that wiki page to be the official coreboot guide. I just installed debian-4.0r2 using qemu-0.9.1(and bochs pc-bios), it works fine.
I'm glad something is working for you. It's easy for tutorials to get out of date.
Another try will be taken for coreboot tomorrow, I would like to write a new doc about "QEMU Build Tutorial".
Your contributions are welcome!
Thanks, Myles
