I found a tool that enables trim support for aftermarket SSD's in Snow Leopard. Its made by a developer by the name oskar groth. Here is his website where you can download the tool(link). Keep in mind this only works with OSX 10.6.7. Anyway just wanted to share it with you guys, i know a lot of people who own aftermarket ssd's for apple computers and this trim support is a big deal to many of them.
