Yep, to the kernel a RAID looks like a complete HD.

83 is, BTW, the standard partition type for Linux, while fd
is the Linux auto raid (automatically Kernel-mounted RAID)

I guess you can simply erase the beginning of the RAID
(/dev/md0) or even make partitions on the RAID -- but I don't
know why you'd want that when you're going with LVM anyway.
