First, identify the kernel .config to be migrated to the new kernel, and get
it into the new kernel source directory as '.config'.
Eg ...
  zcat /proc/config.gz > .config or
  cp /boot/config-2.6.28-xyz .config or
  cp ~/my_brave_rt/2.6.28-rt11.config.good .config

Run 'make oldconfig'. That will stop when it encounters a new option that needs
an answer, so it's scriptable but not entirely automatic.

Then build && install new kernel.
