[ltp] double checking Debian's 686-pae vs. -486 probe

[linux-thinkpad@linux-thinkpad.org]

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.
