>Description:
	I've tested the netbsd-7.0_PATCH GENERIC kernel with my 6.1.5
	installation. I can start X using the driver x-video-intel.
	Works fine, mplayer can use XV for scaled full-screen (instead
	of boxed as with netbsd-6 kernel+video-vesa) output.
	xrandr can switch resolutions on the LCD panel and VGA output 
	etc. (which wasn't usable with vesa).

	However, switching back to a WSCONS text terminal (ctrl-alt-F1
	etc.) shows only black. (but I can blindly log in and run
	echo ctrl-g to beep). I can switch back to X11 (ctrl-alt-F5).

>How-To-Repeat:
	ctrl-alt-F1
>Fix:
	unknown.
