No mouse, No keyboard after upgrading to xorg-server 1.7

If the mouse and the keyboard are not working anymore after upgrading the xorg-server, you have probably forgot to rebuild the xorg-drivers. On a gentoo box find the drivers with:

qlist -I xorg-drivers

Emerge the the drivers on the list.

e.g.:

emerge -v1 x11-drivers/xf86-input-evdev x11-drivers/nvidia-drivers
