The Darwin PPC cd is definitely something you should download. I tried it today and was blown away by the results. I was actually able to see the Apple logo displayed in QEMU! This cd image is free and would allow you to actually test some of the patches yourself. Here's the link: http://www.opensource.apple.com/darwinsource/images/darwinppc-801.cdr.gz
This patch is what allowed me to go so far in booting:

I could post the CIF, but it is huge. The above patch is definitely needed.

The above indicates a larger problem - the open of output-device failed somehow. You don't want to just drop output, you want to figure out why that failed.

According to this page: http://lists.openbios.org/pipermail/openbios/2011-August/006620.html, bootx is setting this variable to null.
I think this patch is all we need fo fix the problem.

Indeed. We need to know *why* it is being set to null. If it is because we are not setting another variable then this patch is not the correct solution.

Interesting. I just tried the above image, but I can get the apple logo with just the get-key-map patch/divide by zero patches. Can you at least send the last few lines of the CIF output so I can compare?
ATB,
Mark.
