If I have minor changes to make I'll edit .config directly in a text
editor, changing "is not set" to "=y".  If I have a greater number of
changes I'll run "make menuconfig", using my original .config, and run
through it quickly (or as quickly as is possible).  No, I don't run
oldconfig; I've found that just running "make" generally throws up any
critical parameters that may have changed and allows me to make adjustments
at that stage.

I'm not saying that this is the "correct" way of doing things, but it's
generally worked for me.  The last issue I had was with iptables, but that
resulted in a harmless warning when booting the new kernel.  Over time I've
had very few problems with this approach.
