For a RAID5, you'll need the dm-raid45 module, which isn't in mainline
yet, much less FC6.  I think Heinz Mauelshagen is still maintaining it.

md is slightly faster than dmraid, and md has better administration
tools.  BIOS RAID has the slight advantage that you can boot off of it,
though iirc there are hacks somewhere on the Internet that explain how
to boot off md.
