PS: I gotta warn you against using the texel knockout technique without discretion. Even with Ex you really want your texels to be not much larger than a few pixels on screen. If the player can get too close they will appear jagged / unnatural. Square without Ex. Bumpy with Ex.
With Ex the player can get a lot closer without things looking weird. And at least with Ex everything is passed thru a linear filter. It just looks strange when some things are filtered and others are not.
Multisampling might help... I'm not sure. But that's a pretty expensive technique / not always available. It's something I plan to add to Ex eventually.
If you are not trying to obtain fine detail, you might be better off using a flat polygon based cutout instead.
Colorkey is great for grass and tree limbs that the player can't get too close to. They don't scale up well.
