I have a fully luks encrypted disk with TRIM support running Debian. It
takes 3 things:

1) add these options to GRUB_CMDLINE_LINUX: allow-discards root_trim=yes
2) add "discard" to relevant partitions in /etc/crypttab
3) issue periodic fstrim commands. I do this once a day with cron

Each distro seems to be different though, YMMV.

Cheers, Jamon
