This is really a fedora/anaconda issue and is probably best in bugzilla
or on fedora-ppc-list.  I've had reports of this on B&W but I don't have
access to one to actually test.

First off can you check to see if the partition table is mac or msdos:

parted /dev/sda print

dir is your friend here. Partition 1 is usually the actual partition
table on apple partition tables.  Dir can help here, eg in OF:

dir /pci@80000000/pci-bridge@d/scsi@4/@0:1,\

Could you also ensure that you have the most recent firmware update from
apple applied.
