A good kernel, like any other software, is a kernel that works, if it doesn't it's not so good.
Have you followed the instructions how to install it, wiping dalvik cache or such?
EDIT: BTW do you have the ftf file for the formware you are using? The kernel is there you can flash it with flashtool no wipes and excluding all other packages.
