Ok guys I figured out how to put in the new kernel.
1.Download the file here http://forum.nitdroid.com/index.php?topic=1006.0
2.rename it to vmlinuz-2.6.28.NIT.06
3.go to /boot/multiboot using filebox and backup the file with the name vmlinuz-2.6.28.NIT.06.
4.finally move the file you just downloaded and renamed to /boot/multiboot.

It worked for me. And if you choose to try it I'm not liable for any issues. try at your own risk.

Changes Ive noticed
1:you can now install apps that wouldnt install before like angrybirds
2:A bit smoother
