I think this kernel has been backported to Jaunty, but I'm not sure, and I can't test because I'm on Karmic. It wouldn't be in the main repository. If it hasn't been backported, I'm not sure whether you can install it separately or would be better off doing a dist-upgrade into karmic.
In karmic, it's in the main repository.
