Do you see any video device listed among the boot messages, like "intvid0
at obio"? Any difference when booting with an older (say, 1.4.2) kernel?
Reason I am asking is because I get the same panic on a Q700 with 1.5 --
here, the internal video adapter is not found. The machine comes up fine
(and is my primary X server) with 1.4Q.

If that helps you, a GENERIC 1.5 BETA kernel has enough of Daishi Kato's
changes to boot my Duo 280c to a working console. I even sometimes get into
X11 if xdm or teh X server don't get killed by FPE exceptions. So, yes,
there finally is Duo support in NetBSD.

You should probably send-pr your problem (there is a web interface on
www.netbsd.org, in case you do not have access to a working NetBSD box).
