Sorry about that. I must say there are way too many emails to read.
Could you reply to the Debian bug number so that I can get a clean
view of the issue.

Then simply please post the output of:

(1) yaboot/ofpath (the one that works)
(2) grub-ofpathname (specify if this with my patch)

from your 11,2 type G5.
