Thanks Paul.  I am putting together new patches to address your feedback 
on style guide, mailer line-feed, and patch format/commit policy.

As far as the build configuration this was tested on is concerned, this 
is Ubuntu 10.04 x86_64-linux targeting i686-oe-linux using a one-off of 
the i686-generic.conf machine targeting a 4MB flash part.

Thanks again,
Ray
