>Description:
The keyboard in X11 is screwed up in that most keys are dead and the ones which work spit out numbers & symbols (very few letters).
The keyboard works as expected on the console and I can try a different layout + variant (ctl/caps swap) using wscons but X11 is not happy by default, with an Xorg.conf specifying just a generic US layout. Tried setting keyboard type to PowerBook or iBook without difference.

>How-To-Repeat:
startx & try to type something on the keyboard.
