Swap problem with F9 PPC

[Guillaume]

The result of fdisk and parted :

[root at ibook ~]# fdisk -l

       There is a valid Mac label on this disk.
       Unfortunately fdisk(1) cannot handle these disks.
       Use either pdisk or parted to modify the partition table.
       Nevertheless some advice:
       1. fdisk will destroy its contents on write.
       2. Be sure that this disk is NOT a still vital
          part of a volume group. (Otherwise you may
             erase the other disks as well, if unmirrored.)

I seems that I have no extended partition ...
It can be apple specific...

And swapon -s .... is empty :(((((
[root at ibook ~]# swapon -s
Filename        Type        Size    Used    Priority

I install 3 times F9, I always use the manual partitionning, and I get I 
times this swap problem...
