yes, i have configured the hw-raid controller to expose the raid array 
as 4k disks (Promise Supertrak EX4650).
i think all modern raid controller support 4k disks and you can expose 
your raid array as 4k disk.(no need for 64bit LBA adresses for large dm-
crypt disks).

would you fix this bug or not? are there any workarounds which i can 
use?
