Good tips.  I made a note of those too.  Honestly, I hadn't even thought 
about the changes needed in the kernel.  It is a 4 core CPU too.

I hope to start the install in the next few days.  I'm still waiting on 
parts to finish the build.  Post anything you can think of that might be 
handy.

Thanks much.
