I have a Fujitsu LH531 laptop, and I can't get X to work.  Help?

The laptop apparently has both Intel and nVidia display adapters, 
and I think Windows switches between them depending on power 
saving options.

I am running NetBSD/i386 5.99.53 (sources dated 2011-06-16 12:00 
UTC).  I should switch to amd64 to take advantage of the >4GB of 
memory, but right now I am using i386.

I am using xsrc (as opposed to pkgsrc modular xorg).  There is no 
/etc/X11/xorg.conf.

The NetBSD kernel reports the following display-related things:

When I run xinit, it prints a few inoffensive things, and then:

[[[

]]]

/var/log/Xorg.0.log contains a lot of stuff that looks reasonable to
my inexpert eye, and then this:

What should I try next?
