Patch is in dm-devel list, hopefully in linux-next soon for kernel 3.1.
http://www.kernel.org/pub/linux/kernel/people/agk/patches/2.6/editing/dm-crypt-optionally-support-discard-requests.patch
Optional cryptsetup support will follow later (currently you have to use dmsetup).
My opinion is that TRIM for encrypted disk is stupid idea, but so many people
requested it... So enjoy shooting yourself in the foot ;-)
Note - it will NEVER be enabled by default.
