Two ways to build a minimal kernel. Try make localmodconfig or make tinyconfig and see what fits your needs best. If this is still not what you need then you have to tweak things using make menuconfig ( can be a real pain in the butt... :)

Stay away from make menuconfig after the initial compile. The first time you use make menuconfig it will create .config for you. As long as you do not mess with the .config you can simply run make and should be able to build just the file(s) you changed.
Keep in mind somethings are statically linked in to the kernel, meaning 'built-in' and if you touch those may trigger a full compile.
To get a faster compile/build use
make parallel build with -j option. Where -j is the number of processors available to you.For eg: make -j4
Also compile for the target architecture only: make ARCH=<your architecture> -jN
UML ( User mode linux ) I have found is faster for reasons yet to be comprehended by me :)
Hope this helps and monikers are good, whats wrong with slap that code with a flying trout eh ?
