The distro shipped kernel is not optimized for a particular processor. So I made a kernel image optimized for core2 processors. I thought it might be useful for others like me who are looking for an optimized kernel for their Debian/Ubuntu systems.
You can download the debs here.
You can also find the instructions for installing/building these images for your systems in the wiki pages here.
Drop a mail if you want me to host a custom kernel you built for any other processors out there. I will be glad to host them and point a link there.
