I recently got in to configuring my own kernel (I'm not sure if you're at
this level or using other people's .config files); it's a bit lazy and maybe
risky not to configure it yourself, but you have to start somewhere.

In any case, the two things I found most helpful are kccmp and
http://cateee.net.  The first is a program to compare two kernel
configurations, and tell you the differences between them, and so on,
displayed in a nice table in X; you can find it in the portage tree.  Before
I found that, I was literally like comparing the files by hand on print outs
and stuff...what a nightmare.  The other is a Debian developer's site, but
there is a large part on kernel configuration (specifically at
http://cateee.net/lkddb/).  I didn't actually find a really easy way to
search the site besides doing a google site-limited query (CONFIG_BLAH_BLAH
site:cateee.net), but once you get to a config page, at the bottom there is
also a google bar with a radio button for just searching that site.  There
could be better places to look for kernel configuration options, but that's
what I was using, and obviously, if you want to configure your kernel, you
should have a place to look up the options, and that database has a basic
description of most (but not all) configurations at least for up to 2.6.26
(maybe later, but that's what I'm using right now).  Maybe other people can
point to other resources?

Also, you should avoid using oldconfig except for really minor kernel
upgrades.  I know this is mentioned in documentation elsewhere, but just a
useful reminder.
