What took the Bears management so long to sign Lovie: are they cheap, racist or stupid?

All of the above I think. They wanted him to prove himself before they gave him anymore money. The Bears din't think that they had any chance of making the Super Bowl since it hadn't happened in a long time. But, when they actually did make it, it sprung something and now they think they have a good thing going. And they really are stupid for thinking he would stay for less money. A coach that gets a team to a Super Bowl, although they didn't win it, isn't going to take a low amount of money and not think about leaving the team.
