System: NetBSD 3.99.20 NetBSD 3.99.20 (GENERIC.MPACPI) #0: Sat May 20 19:16:43 PDT 2006 i386
Architecture: i386
Machine: i386
(Currently running i386 because that *does* work.)
	Intel D945GNTL motherboards with built-in video based on 
	"Intel® GMA 950 onboard graphics subsystem" with or without a
	PCI nVidia TNT2-64 video card installed generates (from memory!)

	cnopen: no console device
	panic: error no /dev/console
	Build your own amd64 installer, or build your own netbsd-3.0_STABLE
	or download the boot1.fs/boot2.fs from:
	... and then try to boot on the following machine:
	Intel Pentium D 930 (dual core, EM64T)
	Intel D945GNTL Motherboard with Intel GMA 950 gfx onboard

	Think onboard video is the problem after reading mailing list notes
	regarding cnopen() failing after iterating incorrectly through
	multiple vga devices, and install nVidia TNT2-64 PCI board hanging
	around into it. Watch it all fail all over again.
	Getting the machine running NetBSD requires plain i386 install disks,
	which work (almost) perfectly, except for a dmesg with lots of ^M in
