System: NetBSD 8.0_BETA, NetBSD-current
Architecture: amd64
Machine: amd64
>Description:
	
Attempts to boot NetBSD-8 or NetBSD-current installer images on any computer 
with a modern NVIDIA card results in a panic saying console isn't found. 
Pleasantly, the keyboard works at the db prompt.
Attempting to boot with -c to try to disable nouveau gives a console on which 
the keyboard doesn't work. After the "uc> ", there's a rapidly flashing text 
cursor. The system does not respond to keystrokes at all.
>How-To-Repeat:
	
Try to install on a system with a modern NVIDIA card. Try to use boot -c on a 
system with a modern NVIDIA card. Tested with GTX 1050, 1080, 1080Ti, but I'm 
sure it affects many others.
>Fix:
	
Replace video card, or make a custom kernel and/or custom installer.
