You have the family wrong for (at least) the Cortex-A8, it's a v7. This probably accounts for some of it's slow relative performance since you probably used incorrect compiler switches.

How were the kernels compiled? Was thumb mode used for the ones that support it?

You didn't mention the cache state anywhere - it can make a big difference.
