>Description:
The following is from i386-6.99.24.  i386-6.1_STABLE show the same
behavior.

On DELL OptiPlex GX110, using on-board i810e graphics adapter,
attempting to start the X server (native Xorg, no xorg.conf)
immediately after a reboot produces the following:

At this point the X server leaves the display adapter in graphics
mode.  The screen displays garbage although the mouse cursor glyph is
rendered properly.  Ctrl-Alt-Fn will switch keyboard focus to another
wscons terminal, but the display is not restored.  I used a serial
console to gather this output.


Subsequent attempts to start the X server produce:

I've saved the "Xorg.0.log" files from the above sessions, but they
don't really reveal much more that what's posted above.

Native Xorg on netbsd-5 works.  An HP Pavilion w/i810e works fine with
netbsd-6 native Xorg.  I've only seen this problem on the DELL GX110s.
(I don't have any other i810e-based machines).

I also have an installation that uses modular/pkgsrc Xorg on netbsd-6.
It displays the same symptoms, but I've not yet captured the output of
the X server.  I expect to do that soon.
>How-To-Repeat:
On DELL OptiPlex GX110 (perhaps other systems with i810e) attempt to
start the X server.
>Fix:
Workaround (proposed, not tested):  Install different video adapter.
