I don’t in any way see how Burke was saying that the spirit of liberty was strongest in the old South; he’s saying that the slave-owners value their liberty the most. But slave-owners were a terribly small minority.

Not quite. He's saying that every member of a society with slavery will value their freedom more. Not just the slave owners.

No, he specifically says “slave drivers.”
