ext3 trim support?

Latest version of linux kernel has trim support however does it apply to ext4 or can ext3 have trim too?

Basically, if it depends on the kernel version and you upgrade the distro to latest kernel version (debian squeeze etc), will it have support for ext3 trim?

This post on the ext4 developers list with patch for elements of trim functionality in ext3 strongly suggest that such work is being done already.
When creating a file system (i.e. mkfs), mke2fs will attempt to "discard" or "trim" blocks not used by the file system metadata. This helps to optimize SSDs or thinly-provisioned storage. To suppress this behavior, use the mke2fs -K option.
