raidtools2 (or raidtools) or mdadm can be used for software RAID in Debian PPC. If you are familiar with setting up software RAID in Red Hat, it will be identical in Debian ppc using raidtools or raidtools2 (except you will have to write the config file, which will be easy if you nab a similar one from your Red Hat system to start with). You'll have to use mkraid to make the RAID devices (e.g. /dev/md0), and you'll have to make a file system in the resulting software RAID devices. I know one can specify devices for software RAID arrays in the Red Hat installer, and the installer does the work. But there's not much to it (with raidtools[2], make /etc/raidtab, run mkraid, format the devices, done). You will need compiled in or modular RAID support in your kernel. I've used firewire hard drives in a Linux PC, and I access them just as I access any SCSI hard drive (they appear as SCSI devices, /dev/sda, etc.). I haven't yet attempted to use the firewire port in my Mac (it's an iBook2, which I now like using after blowing away OS X ;).
