After update, just a black screen

[Mick Bert <MickBert@posteo.net>]

Very bad!

After the complete update, since long time (see, the other email), I got 
from my iBookG4 just a black screen.

I can see the boot logging until the graphic card initialization, then I 
have no way to interact. I also tried to load the old kernel (from 
yaboot menu), but the result is the same.

Apart from suggestions on how to fix the whole issue, the first 
information I need is how can I boot the system in a text console, 
without loading xorg, which I suppose is the point.
