config.h doesn't exist until you do 'make config' (or oldconfig, or
menuconfig, or xconfig) in the kernel source tree. It is *not*
sufficient to install the kernel sources; you need a valid
configuration, too.

If you're using a distro-supplied kernel (i.e., not one you've compiled
yourself) look for their config file is /proc/config.gz or
/boot/config.gz. Gunzip it to /usr/src/linux/.config (assuming the
kernel sources are installed in /usr/src/linux), cd to /usr/src/linux
and do 'make oldconfig'. You'll now have a config.h file matching your
currently running kernel.

If you're using a custom kernel, you should still have your own .config
file around. Also, remember *do not* do 'make clean' after builing your
own kernel if you have to build other modules outside the kernel source
tree. 'make clean' will (among other things) get rid of your config.h.
