Really? Funny, because IIRC RAID autodetection does not even exist in
2.2.x kernels. Perhaps you are referring to vendor-patched kernels --
some distributions ship 2.2 kernels with RAID patches applied.

What would be the point? Autodetection is only needed for mounting the
root filesystem. After root is mounted, you can use raidtools.
