I think I've reproduced the crash on my Quad G5 by using your config
with some things tweaked, but I don't get any output on the screen :/

Do you mind booting the commit above and taking a photo of the oops and
attach it here. The oops you transcribed didn't entirely make sense,
probably due to a typo here or there, so a photo would be best.
