monitor went black after updating kernel to 2.4.18

[svante <svante@demonbox.com>]

Hi all,
Im running a Apple Macintosh 9600/300 Powerpc and just updated my debian 
kernel to 2.4.18. Sudddenly the display dont come on at startup. Besides 
from that everything is working fine. I figure there's some setting in 
quik.conf I need to set to get it to see the graphic card, right? Can 
someone help me with this, I got the below kernel boot log:
