Just compile them all as modules. You will not need to modprobe them
manually.

I guess that's the vanilla kernel.org config.

You can use a config from and old kernel. New config options will take
the default values. If you type `make oldconfig`, it will only ask for
the not yet configured config options. This is pretty convenient because
you don't have to browse through the zillion options in the gui.

You can possibly use these too. Better yet, get a more recent one for
2.6.16 or 17.

Use the diff command. For gui people, there is a nice tool called meld.

Debian has this package:
linux-source-2.6.17 - Linux kernel source for version 2.6.17 with Debian patches
If ubuntu has older versions only, get that and extract the .config from
it.
Alternatively, if you still have an ubuntu kernel installed, you can grab
it's config from /boot/config-xxxx
