i'm pretty sure this won't require a new kernel -- just changing the
.config file, and running "make dep" should do it.  but a short note
about "make mrproper" is in order.

as most people know, make mrproper does a complete source tree
cleaning, including removing the current .config file, so it's a good
idea to back that up.  but in addition, make mrproper removes a
small number of include files, like autoconf.h

what this implies is that, if you do make mrproper, it's not enough
to just restore the .config file.  you still have to do one of
make config, or make menuconfig, or make xconfig, or make oldconfig,
to restore the deleted header files.  try it and see.

anyway, you don't have to be that drastic.  just changing the 
config file, and going forward from make dep should be sufficient.
