Maybe you should keep on reading before having a go. Check post #55 in the ICS builds thread. They want to modify it so that swiping the apps does the same thing as long pressing back. Which I don't think anyone else is doing, so doubt away.
And if he wants to keep his kernel without Voodoo, which I don't see the point of either, then it's his call. Use a different kernel if you don't like it. Don't come and have a whinge here man, not cool. You have a dig at any other kernel devs who don't want to put YOUR suggestion into THEIR work which you are using, for free?
