Based on what I can gather, cryptoloop is deprecated in the 2.6 kernel, and the new interface (dm-crypt) is not yet fully supported in userland. dm-crypt is on the TODO list though!
Why is this bug a WONTFIX? All it requires is the correct patches for the 2.6 kernel, documented here: http://www.linux.org/docs/ldp/howto/Cryptoloop-HOWTO/userspace-tools.html Sure it's deprecated, but it still works, and (a) until the userland dm-crypt tools are supplied with Fedora this is the simplest way to get a crypto filesystem, and (b) the FC2 version of losetup is for the 2.4 kernel - it would seem stupid not to patch it to be compatible with the 2.6 kernel which comes with FC2.
