As far as I know, the 'boot-device' setting doesn't care about the
partition number, it just wants your device, i.e. 
"/pci/mac-io/ata0/disk@0,0" , if that's what you get from OF
(maybe try "@0:0" also ?)

On the other hand, the 'boot-file' setting requires the root partition
and the path to the kernel, but you can usually just put the label you
defined in quik.conf (e.g. 'Linux'). If that doesn't work, you should
try filling in the full path : e.g.
"/pci/mac-io/ata0/disk@0,2/boot/vmlinux" 
(or maybe "/pci/mac-io/ata0/disk@0:2/boot/vmlinux")

that's your device, right ?

and that's the full path... i don't get the issue
