Can't get TRIM working on SSD

In /etc/fstab both the / and /home are ext4 with the discard,noatime options added

If I run the hdparm tempfile test it doesn't result in all zeros, but in Ubuntu it does with the same fstab options.

The Ubuntu kernel is 2.6.35 and Arch is 2.6.38 if that matters. Am I missing something out for Arch?

P.S- I'm using OCZ Vertex 2. In the SSD section of the Arch wiki it says-

"Warning: Using an OCZ Vertex II SSD (supports TRIM) and kernel 2.6.37.4 on Arch, some people experienced trouble with the discard option: all changes made to the filesystem would disappear after a reboot! According to this, discard is disabled by default because it not stable enough"

I'm on a newer kernel, and I haven't had any unsaved changes happening, but could this be something to do with it?
