I'm not sure if I've parsed that correctly - you say that the
desktop used to work, but the new kernel broke it ? I assume you
mean that the mouse and keyboard stopped working in xorg ?
On the desktop, did you take the working config from the old kernel
(hopefully, you have it in /proc/config.gz), copy it to .config in
the new kernel source, and then run 'make oldconfig' ?
If you did, what versions were the old and new kernels ?

This is what makes me think I've misunderstood you - now you seem
to be saying that the desktop has no problems ?
Anyway, for your wife's system, have you set CONFIG_INPUT_EVDEV in
the kernel config ?

Surely 10-evdev.conf was installed by the xorg-server, and you
installed 11-keyboard.conf yourself ? These are how the server is
able to tie events to their sources. Actually, taking a quick look
through the rendered book I can't see where 11-keyboard.conf is
mentioned. I'm sure we mention it somewhere, because I believe that
without it xorg should still work, but with an American keyboard
layout which is not useful for everyone.
I think 10-evdev.conf should be ok - it comes from the server, so
it should match what everyone else has. For 11-keyboard.conf you
should have something similar to this:
Section "InputClass"
Identifier "keyboard-all"
Driver "evdev"
Option "XkbLayout" "gb"
Option "XkbModel" "evdev"
Option "XkbOptions" "ctrl_alt_bksp"
MatchIsKeyboard "on"
EndSection
Obviously, you will not want "gb" for the layout. I don't know if
there are multiple german keyboard variants, but "de" seems a
likely value to start with.
Looking at my own Xorg log, I think all the useful information for
debugging goes to stderr and appears on the console, not in the log.
So, try using 'startx 2>xorg-errors'.
Do you have MagicSysRQ enabled in the kernel ? If you do (it's
under Kernel Hacking), you can sync with Alt-SysRq-S, wait, then
umount with Alt-SysRq-U and boot with Alt-SysRq-B : those keys
should, I think, still work even if Xorg doesn't find the keyboard.
If you have that, the Sync and Umount ought to allow the xorg-errors
file to be updated.

I think those two 'No input driver' messages are the signs that the
input devices are not configured correctly.
