Did not manage to resize an HFS+ partition on a powermac G5.

Dear lists,

I am trying to install Debian on a powermac7,3 at work, but I did not
manage to resize the main HFS+ partition. Although I have a backup, I
would like to avoid reinstalling MacOS X. I saw on the web reports from
2005 in which an HFS+ partition was sucessfully resized with the
debian-installer, so I wonder what I did wrong.

I am using the netinst for Etch, in which parted is version 1.7.1. when
I try to resize with a command such as "resize 3 100GB 50GB", I got the
following error message:

Error: Unable to satisfy all constraints on the partition.

Here is what I know from the disk

I disabled journaling with  sudo diskutil disableJournal /

Any idea ? I am a bit frustrated of not being able to use the packages I made...

Have a nice day,
