More debugging on karmic:

/etc/acpi/events/asus-wireless

is the event that is responsible. I looked into

/etc/acpi/asus-wireless.sh

and found that somewhere in toggleAllWirelessStates() the video configuration is destroyed. This method is imported from /usr/share/acpi-support/state-funcs

Thus, I am assigning this bug to acpi-support.
