Err, no.  It's the result of using Portrait Video card.  b/w
mode is selected on both monitors.

That's it!  I ftp'd X server from ftp.netbsd.org, and it
works on internal video.  My X server was corrupted.
Modification date of the damaged file is 13 Jul, so I think
it corrupted when my system crashed.

I'll try if it works on the NuBUS video card and report the
result later.
