This sounds like a problem one has with upgrading kernels too. In our
BSP there's this:

  PTXCONF_KERNEL_CONFIG="kernelconfig-${PTXCONF_KERNEL_VERSION}"

So there's one config for each kernel version. When upgrading I do the
following:

  * `ptxdist kernelconfig`
  * "Load an Alternate Configuration File" – Here load your old config,
the in background called 'make menuconfig' for the kernelconfig handles
new options.
  * Do your settings or check your old ones.
  * "Save an Alternate Configuration File" – Enter '.config' here.

ptxdist handles copying .config to
kernelconfig-${PTXCONF_KERNEL_VERSION} in both directions, at least this
is what I guessed from the behaviour.

So you do not only need to load your old config but save it to .config
(without path before). You can now call `ptxdist kernelconfig` again and
your config should still be there.
