Canek, how to handle changing configs?

AFAI understand I do:

eselect kernel set x
cd /usr/src/linux
make menuconfig
(SAVE .config)
cp .config /etc/kerninst/kernel-config
kerninst

... right?

I am currently struggling with a kernel not showing /dev/kvm ... and
toggling kvm_amd on/module ... etc

Thanks, Stefan
