To help identify the problem, i followed the steps from:
http://mail-index.netbsd.org/port-macppc/2004/08/30/0015.html
to get more information on the issue.
I tried that with a -current kernel, on a very similar Powerbook 6,8
(the only difference is the 1GB DIMM), with both ofwboot.xcf and the
kernel being on a small HFS partition.
Here is the output, i hope it can help to get what is wrong here

Regards,
antoine
