Have a look at this page: https://wiki.gentoo.org/wiki/Kernel/Configuration In particular, take notice of 'make localmodconfig'. Once you have a customised kernel as you like it and it boots successfully, you can copy your good /usr/src/linux/.config to any subsequently emerged new gentoo-source kernel trees and run 'make oldconfig' thereafter, to only have to deal with new kernel options.
