Where is my mind?

I could have sworn that I installed a new kernel yesterday. Either I'm losing my mind or something is fubared. No, look I can see the .deb in the archives...but apt-get still wants to download it? Uh, no wonder the old nvidia driver seemed to magically work. Whatever, I think I'm pretty safe from local DOS attacks, unless I've suffered some serious break with reality.... In which case, I have more pressing issues than upgrading the kernel :D
