newb question about compiling a new kernel

I'm trying to compile a kernel for my Crux Linux install.

I figured I'd do a 'make defconfig' to setup a .config file with the default configuration and then try to add anything I will need for my specific system.

I found a script that scans my system and prints out a list of any current modules I am using. That way I can make sure to add these to my new kernel. It looks something like this:

My question is: Is there a way to add these to my current configuration without having to go into 'make menuconfig' and search for each one?

It's not too hard to search for many of them. But the ones with short names I'm not finding. Like ac.ko for example. 'ac.ko' returns 0 search results and 'ac' returns anything and everything with those 2 letters in it.

Any other tips on compiling a kernel are welcome too!

make localmodconfig
make localyesconfig

This should update your config based on the modules you currently have loaded in the system.

See the 2.6.32 release notes for more.
