Interesting. I think this shows--a little--how the sports media focuses on brands it knows. So Auburn, Florida State, Clemson, Penn State, Notre Dame, and Nebraska get bumps because the media (and fans) are used to seeing them ranked, and ranked high. It would be interesting to run an analysis of how long it takes the teams who have the most all-time AP poll appearances to fall out of the Top 25 relative to teams without that history. Compare the results for say the top 25 against the not top 25. I bet it's also a sliding scale, meaning a top-10 team all-time gets a lot more leeway than a top-20 team.
