OK, it was unmaintained last I looked.
I suggest scanning the kernel-raid mailing list.
raidreconf has about 50% success rate - it can work.

The problem is that that success rate means you need to take a backup - 
and once you've done that it's quicker/easier to blat the raid5, rebuild 
and restore.
I couldn't, in all conscience, recommend it.
