All,

Please test for Devin if you can. I've reviewed the changes and they
look good to me.

I also know Devin will make things better or drive himself insane
trying. ;)

Thanks ONELAN for the support! And thanks Devin for finding time to
take on the job.

Thanks for taking the time to review. As I'm sure you noticed, some
of the changes can probably be used for other boards as well, but at
least initially the goal is to get the 1600 working well without
breaking any other products.

Oh Andy, you know me so well. ;-)

As of this point, we're seeing some mixed results - some are reporting
improved performance, and others are experiencing a regression. I'll
get it nailed down though.

Devin
