[PATCH] nvidia fbdev: fix powerpc xmon scribbles
xmon writes garbage on the screen because the nvidia console driver has changed the line pitch from what the firmware set it to. Fix it by making the nvidia driver inform the btext engine (which xmon uses if the screen is its output device) about changes to display resolution.
