We must be using very different d-is!

I've never seen an option to create a partitioned mdraid array for
either squeeze or wheezy.

Furthermore, grub2 in squeeze cannot recognize partitioned mdraid
arrays; squeeze has grub2 version 1.98+20100804-14+squeeze1 and
partitioned mdraid support was introduced in version 1.99-1.
