Xorg 7.7 suddenly lost the keyboard

After digging a bit deeper in the issue the most revealing symptom is
this error in /var/log/Xorg.0.log...

[   585.774] (II) Using input driver 'kbd' for 'Keyboard0'
[   585.774] (**) Option "CoreKeyboard"
[   585.774] (**) Keyboard0: always reports core events
[   585.774] (**) Keyboard0: always reports core events
[   585.774] (**) Option "Protocol" "standard"
[   585.774] (**) Option "Device" "/dev/kbdmux0"
[   585.774] (EE) Keyboard0: cannot open "/dev/kbdmux0"
[   585.774] (EE) PreInit returned 8 for "Keyboard0"
[   585.774] (II) UnloadModule: "kbd"

That "PreInit" is apparently kbdPreInit() and the returned code 8 stands
for BadMatch.

What should I make of this?
