I can advise not to do that, it always looked like an ugly hack to me. Just stick with the standard way. What I do is just create a small md raid for /boot (this needs to be raid1) and make everything else one big md raid with lvm on top. Works great for me and it's very flexible due to lvm and ext4 (that means on the fly filesystem resize among other things).
