  This will work, more or less.  It will download the 3.2.6 kernel and run its
configure with your 2.6.32 .config.  That will give you a lot of questions on
the console about config options which exist in the 3.2.6 kernel but didn't
exist yet in the 2.6.32 kernel.  So not necessarily the most efficient
approach.

  Yes you can: use the "custom tarball" option that I mentioned in my mail.

  You have to configure that separately for buildroot and for crosstool-NG.
AFAIK buildroot doesn't allow to give a directory, so you'll have to make
a tarball from the directory first.
