It is probably easiest to take the .config file of the latest kernel of
the distribution you are using as a starting point. In that case you
know that this starting point at least works on your machine.

(I remember seeing tutorials that show you how to generate a .config
from scratch. I wonder whether anyone actually does that. It should be
quite a bit of work for an uncertain outcome. Ie, you might end up
trying quite a few configurations before hitting one that works
reasonably for your machine.)

Hope this helps,
