I've updated the default .config for 2.6.25.  I've enabled a handful
of features by default and also some kernel debugging features.  I've
also changed many of the defaults so that everything possible builds
as modules instead of built-in.

Here's a few of the features that are now on by default:

 - tickless
 - high-res timers
 - preemptible kernel
 - EABI support
 - new GPIO/LEDs support
