No Hard drive found error with mac-fdisk in install PPC debian

[Francis Parent-Valiquette <franck.rules@gmail.com>]

Hi everyone

I'm an old user of debian last month I bought a mac PowerBook G4 and
I'm trying to install the Power Pc distro of debian on it I follow the
how-to of Branden Robinson
That could be find on this site
http://people.debian.org/~branden/ibook.html#run_installer

When I try to use the mac-fdisk partioning tools It doesn't see my
hard drive. Is there any patch or something to disable in the Open
firmware that could help me ?

Thanks

Franck
