I have to revert the patch below from mmotm 2012-07-20-16-30 or
next-20120720 in order to boot on the PowerPC G5: otherwise it
freezes before switching to the framebuffer console - but I'm
not certain where because that initial console doesn't scroll
(there are mpic messages at bottom and at top of screen, probably
later messages at the top but I don't know the sequence).

Remind me your G5 variant ? (/proc/cpuinfo will do). I'll have a look
tomorrow (and thanks for testing !).
