yeah, I think it's only looking through that list. which is missing a NEI/ Codechicken listing. I plan on cobbling a 1.6 myself once enough Mods have updated, just for testing, but NEI is on the top of my must have list. If I'm gonna deal with block ID issues i have to have that mod.
personally, i like this link better... it seems (to me anyway) to be laid out much more logically, and easier to find the "exact" mod you're looking for... YMMV, but it works for me
