Put a partition for /boot, swap and RAID5 on every disk then do RAID1 across the /boot and swap partitions. A 4-way mirror is a bit excessive so you could just put /boot on two of them and swap on another two. As long as the partitions you want to put into a RAID1 or RAID5 are the same size there will be no issues with Linux software RAID. Also consider RAID10 rather than RAID5 if you can spare the disk space; it has better performance and better redundancy.
