Recently Debian sid split the kernel into these two packages, linux-image-2.6.39-1-486_2.6.39-1_i386.deb linux-image-2.6.39-1-686-pae_2.6.39-1_i386.deb My Thinkpad ended up being told by the installation scripts to use -486. But my Thinkpad isn't really very old... how can one double check to see if the decision was correct? I can't figure it out even after probing the .debs to find just where they probe the choice.
