They are not listed in /proc/bus/input/devices. The mouse in X is not moving, keyboard is dead, etc. All I can do is reboot and hope. Below you can find the diff of /proc/bus/input/devices between a bad and a good start. udev is 146-5 (included with Debian Sid). Any helpful hints would be highly appreciated. Of course I can send you the .config, if there is some interest.
