I meant from a user viewpoint. It is just a mish-mash of essentially unrelated
questions. I'd prefer to see options moved into menus that describe them.
Ideally about a screen length of options (for variable screen resolutions and
xconfig vs menuconfig :-)

So mice and joysticks are kind-of input things, so they belong with other
input config options.

Similarly, DRM and AGP are video options, so they belong together in a video
section (certainly not in a character device options section). Maybe with
other console options (although the concept of console is a bit strange in
the era of desktop unix) like framebuffer and VT.

Serial can bugger off by itself.

ftape is a mass storage thing, and belongs with other mass storage options
like block devices, ide and scsi.

i2c and watchdog cards are basically for system monitoring.

I think that I've explained it poorly. I'll patch.

That is where most of the input stuff came from :-)

My main concern is that by 2.6, I don't want the current mess with Config
options. I want something that is logical and makes sense to people. Right
now, the only reliable way to get a build is to either check every menu (and
submenu, and subsubmenu), or to take a previously working config for that
machine, make oldconfig, and hope for the best.

That sucks.

We go to all this effort to write clean, beautiful code. Then we make it nigh
on impossible for non-gurus to get the most out of it.
