i386 to i686 kernel

[justajeeper at comcast.net]

I get this error when I try to enable the i686 kernel:

root at Bad-Mamma-Jamma:/home/justajeeper # sudo apt-get install linux-2.6.1.8-3-686
Reading Package Lists... Done
Building Dependency Tree... Done
E: Couldn't find package linux-2.6.1.8-3-686

any suggestions?
