i think i may have a similar issue on a box that has been tracking etch for a
while with a british keyboard and developed the "can't switch out of x with the
"CTRL-ALT-Fx" keys sometime while tracking etch (i don't recall exactly when).
i mention this because it means the issue of keyboard layout configuration
changing with the result of broken vt switching out of X does not just affect
swiss german keyboards but some others as well.
the section for the keyboard
Section "InputDevice"
Identifier "Generic Keyboard"
Driver "kbd"
Option "CoreKeyboard"
Option "XkbRules" "xorg"
Option "XkbModel" "pc105"
Option "XkbLayout" "uk"
EndSection
a recent etch install with a british keyboard which does not suffer this
problem has gb instead of uk (i can't test if changing it on the first install
fixes it right now due to lack of physical access)
