I do have the type set to 0xfd. Others have said that auto-assemble only works on RAID 0 and 1, but just as Justin mentioned, I too have another box with RAID5 that gets auto assembled by the kernel (also no initrd). I expected the same behavior when I built this array--again using mdadm instead of raidtools.

Any md arrays with partition type 0xfd using a 0.9 superblock should be auto-assembled by a standard kernel.

If you want to boot from them you must ensure the kernel image is on a partition that the bootloader can read - ie RAID 0. This is nothing to do with auto-assembly.

So some questions:
* are the partitions 0xfd ? yes.
* is the kernel standard?
* are the superblocks version 0.9? (mdadm --examine /dev/component)
